So after recently watching Back to the Future again, I knew I had to make a video breaking down some very convincing theories on the time travel movies! Hope you enjoy the video and have a fantastic day, see you all next time!

[@brianp6682]

biff got into the car detailing business because in high school, his car kept getting filled with manure and he became an expert at scrubbing every inch of a car inside and out.

[@TheGuruStud]

He paid to have it cleaned (at least the first time). Although, I guess you still could be right, b/c he gipped the detailer, so perhaps he was forced to clean it. Also, he's into cars, so it's a natural career opportunity (and requires little high functioning brain activity lol).

[@benjaminventuri1472]

Maybe Biff couldn’t afford the $300 bill and was forced to work off his debt. Which later became a job and finally his career?

[@jwalster9412]

He just won't go near any cars the got covers in manure.

[@rafaelfiallo4123]

I always wondered where he got $300 in 1955. That was a big chunk of dough for an unemployed high school student. $300 would have bought 5 of those 1946 Ford convertibles in 1955

[@venialgaming4295]

[@Dream0Asylum]

I don't buy the "Biff is clever" one. I think after George knocked him on his ass, everybody started standing up to him and his unjustified confidence never recovered. He had to adapt by being what he thought (as kind of a sociopath) nice was - just nonthreatening as hell. Meanwhile, his darkness never really went away, it was just hiding under the camouflage he had created to get by.

[@theduffster1985]

I was thinking the same thing. Every one heard that George McFly stood up to him so everyone began to stand up to him also.

[@ThatAnArchyDude]

Exactly

[@takadouglas]

Yeah the rest are very plausible but theres lots of holes in the last one. This also doesnt mention anything about how Biff is still a bully in 1955 after the knockout by George, and you can see this in the clips they show from BttF2. There would be more dialogue from Old Biff if he was obsessing over Marty this whole time. He figures it out in 2015 when he sees the flying Delorian and remembers it disappearing in 1985.

[@ScallopHolden]

He was working for the guy. He still didn’t like him but he was his boss so he had to behave.

[@mgbmusic99]

Yeah I don't buy the last theory at all. If biff was so obsessed with Calvin Klein, why not tell young Biff about him by name. Instead he just says "a kid or an old man".

He might have thought that NOT reading the letter and following the instructions might itself lead to a paradox.

@@christopherheckman7957 Thats true, but from the perspective of 1955 Doc, he doesn't do all that much in BTTF 3. They get the time machine out of the mine and he sends Marty back to 1885, thats it. The rest of the movie deals with 1985 Doc. This does though raise the question, why wouldn't 1985 Doc know and therefore prevent himself being struck by lightening, having in 1955 gone through the process of seeing Marty turn up a second time and recover the time machine from the mine etc.

[@christopherheckman7957]

@@chrisjohn4605 Easy. Because if Doc isn't struck by lightning in 1955, he doesn't go back in time, and a paradox results. If anything, he would have been motivated to add a lightning rod to the Delorean, to guarantee that he does get struck by lighting and goes back in time.

[@lavahawke46]

This first theory about Doc realizing things is unnecessary. Doc had an idea that Marty was going to tell him how he died because he is a very smart man and he heard the things Marty kept saying to him. But when Marty came back afterwards telling him how Doc had ended up going back to the Old West, he would have realized that he did not die. He would also see that this Marty was not sad about anything. That would tell him that he didn't die and it was okay to read the letter and take whatever precautions would assure that. 1985 Doc must have had a lot of secrets though!

[@DavidBrocekArt]

I like how the first movie started as a "50's nostalgia" movie and then sneakily shifted into an "80's nostalgia" movie

[@whitworth5s248]

I have a theory that Marty's sudden personality change between 1 and 2 ("Nobody calls me Chicken!") is his personality reverting to the personality of the Alternate Marty; the one we see leaving the Lone Pine Mall parking lot at the end of 1. Alternate Marty grew up with confident parents, and because of this, he grew up with a bit more attitude and a more fiery temper. When Marty returns to 1985 for the first time he's the same guy, but after a short delay, the changes his alternate self makes in 1955 (mostly the same btw, as we see at the end of 2) the changes to the future ripple out and change our Original Marty into the Alternate Marty. One key clue to this is that Marty never acknowledges memories of his original 1985 parents after the final scene in 1. At some point after he sees his new truck for the first time, but before he travels to 2015, the ripple catches up to him, and his memories of his old life are erased. He still remembers Doc and time travel, because that Marty would as well. But from that point forwards, he only remembers his parents as Alternate Marty would remember them, despite having only seen them once for about a minute. When he meets his mother again in 1985A, he seems surprised to see that she's an alcoholic, even though this version of his mother is pretty much the same as what he grew up with, more or less. And he's shocked to believe that his mother would leave George. If he remembered his father as being a wimp for his entire life, maybe it wouldn't seem so shocking to Marty that his mother might go for the guy across town with his own skyscraper.

[@SODtv]

This actually makes my brain hurt trying to think about it, but I see where you are coming from.

[@no.one.a113]

That is a really good theory.

[@nothing-oj1sz]

[@SeeminglyOdd]

It makes sense as we see it happen with the newspapers.

[@TAKTAK_Toys]

This is technically where their is a paradox in time travelling in the films. The sports Alamanc should change based on the time travel rules of the original film, but the second film has slightly different time travel rules : for example: old Biff comes back to 2015 after giving himself the Almanac in 1955. He’s able to do this because in 1955 Marty and Doc have already got the Almanac back from Biff and corrected the timeline, but based on these rules, the photograph Marty has shouldn’t change in the first film, because Marty has already got his parents to meet and fall in love and correct the timeline .

[@rallyfeind]

@@TAKTAK_Toys Marty is the only one from the original timeline so I think he is the timeline now, if that makes sense. Being outside of time has made him the determinating factor for all the secondary actions of timetravel in this universe. It is like he is the only one that is actualy in synchronization so nothing is locked in place and time unless he is part of it now. The same is true of Doc being shot at the point of leaving the first movie. He never saw him die for certain so when he was wearing the vest it could be original but we are made to think it was an alteration Marty caused completely. The whole second movie is kinda nonsense in that it was all caused by Doc not learning the lesson about sending a person and not leaving a letter with intructions that he learned by getting shot like the letter said. They learned nothing till the end of the 2nd when letters are back in play.

[@billyyank2198]

I disagree with the last theory. I think it is far more likely that Biff tried to keep his tough guy status after George knocked him out, but the rest of the school basically treated him as an outcast since he was beat up by the wimpiest guy in school. It turned the tables on the relationship between George and Biff, making Biff subservient to George. In 2015 when Biff saw the Delorean, he mused that he hadn't seen a flying Delorean in 30 years. It was only after he saw two Martys and then listened in on the conversation between Doc Brown and Marty that he put two and two together. His decision to travel back in time himself was spur of the moment. How awesome is it that a trilogy is still making us dissect every part over 30 years later? Not even Star Wars has this level of complexity.

[@JeffDeanTheDeanZone]

We see that the punch did nothing to change Biff in BTTF 2. After he wakes up from being decked, he goes and finds Marty and kicks the living crap out of him. If anything, George's punch made Biff more dangerous. This is a plot hole I address in my "Real Mistakes of Back to the Future." Once they got that book away from Biff, Doc in 1955 was in immediate danger. We saw how Biff relentlessly pursued Calvin Klein for doing 300 bucks damage to his car. Imagine how he would have pursued Doc Brown once an Almanac that he knows can make him a fortune is stolen from him. How would Biff know to track down Doc? Well, he dragged Calvin Klein out of Doc Brown's car in the dance parking lot. It was, at that point, known that Calvin Klien is associated in some way with Doc Brown. In searching for the book after it was stolen from him, he would have remembered the warning from the old man who gave it to him, about a crazy scientist and a kid trying to take the book from him. Stealing the book from Biff would have created a whole new and far more terrifying timeline where Doc Brown would probably have to leave town in order to avoid attacks from Biff Tannen for stealing his futuristic Almanac from him.

[@Nintenblox]

I think the best answer is that Biff doesn’t what bad times with George after that event. He’s still an terrible person like we see in 2015

[@garyhall2770]

At one point in time there were 4 DeLoreans in 1955. 1. The one Marty went back in time with. 2. The one Marty and Doc went back in time with. 3. The one Biff went back in time with. 4. And finally the one in the cave.

[@mephostopheles3752]

@@lookbovine Right, but I think what they’re trying to say is that the DeLorean from 1885 wasn’t buried under the mine UNTIL the flying DeLorean was struck by lightning, because it hadn’t been sent back in time to become the 1885 DeLorean yet. But the logic of that assumption is sorta sketchy, because changes to history seem only to occur as a result of meddling by time-travelers, and the DeLorean was sent back unintentionally by a lightning strike outside of their control. In other words, there was a point some period of time before the lightning strike at which the time-travelers’ actions no longer had any effect in changing the outcome of the DeLorean being struck by lightning and sent to the past, and at THAT moment, the 1885 DeLorean would’ve appeared buried in the mineshaft, and from that moment until the lightning strike, both instances of the DeLorean coexisted in the same part of the timeline. Assuming this period of time is long enough, then the other two DeLorean’s (2015 Biff’s DeLorean and Marty’s original 1985 DeLorean) could very well also exist alongside these ones, proving the theory correct. But we can never know because we don’t know what actions, if any, could’ve prevented the DeLorean from getting struck.

It's funny because ever since I was a kid watching these movies, I always thought that was a given.

@@dylanhughes572 Except they are not actually changed in real time. Honestly, the more you look at the BTTF trilogy, how it treats items from the future is more like probability waves. In the movies with photos, the changes were visible but not definitive. The more it looked like his parent's were not going to get together the more of the photo faded away, but as soon as the key point happened and it was a lock that George and Loraine were going to get together, they came back quickly.

I think the same thing for why Buford showed up at the town party to shoot doc a few days early. Doc likely wasn't originally planning on going, but since he met Clara, he figured he'd go. So Buford found him and tried to shoot him earlier than in the original timeline. But then again, Doc wouldn't have originally found Clara and saved her if Marty hadn't been there, so, who knows.

[@shinjisan2015]

Maybe not at the dance, but it still fits that Biff assaulted her around that time. He could have even done so later that night as he was drunk.

@@_Ike Buford said at the dance that the last man he'd shot with that gun had taken 3 days to die, so it would have been true for Doc as well.

This is one of my favorite movies but I have always thought that the script missed the fact that since the alternate present is much better, Marty's family wouldn't be living in the same house as it is the same house when they weren't doing so well. Everyone now is a different person except Marty.

[@charleslee8313]

unless... George and/or Lorraine's parents bought the couple their home (as a newlywed present), and they kept it as a reminder of family. Since Lyon Estates was just being built in 1955, a new home in that area would have been rather cheap, so George and Lorraine would have been married after college (let's make it 1960, at the earliest), so either his parents or hers got enough money by that point to get a nice, modest home in the newly developed Lyon Estates, so that they could stay in Hill Valley, and each other's in-laws could come by.

[@Seriona1]

I don't see any reason for them NOT to be in the same house. Marty had changes to his own parents but he only changed their behaviors and nothing beyond that to make a dramatic changed. He just made his dad have balls and he became the writer he wanted to be and thus Lorraine isn't a drunken mess due to hating her life. I don't see how either of that would of changed anything else.

IDK, I don't even think the scene in the car would happen in the original timeline. Most likely in that timeline Lorraine didn't even buy the sexy dress and didn't try and seduce George in the car, so they went straight into the dance and the rest follows how she depicted it at the start of the movie.

(It's only popularity is ironically because it was the time machine in this movie) Now imagine a world where no BTTF came out, that means the DeLorean would be even more niche, so seeing a DeLorean do something incredibly and then seeing one pop up 30 years later would definitely get your gears grinding.

He would've returned to a different timeline, just as Marty did when he went back to 1985. The plot gave us a GIGANTIC hole and we all just went with it.

[@Salsuero]

@@flightofthebumblebee9529 He wouldn't have been able to return at all. Disappearing isn't enough. The nanosecond that he handed over that almanac, that's it. He shouldn't have faded out at all because he was still Biff. He changed the timeline. Why would he actually cease to exist? It's not as if he killed himself in the past. He would have simply returned to a different timeline than the one he left that would have looked a lot different -- according to the rules of Back to the Future -- where Marty made changes, and his future was different -- he didn't fade away. This is why time travel is totally absurd. And his cane was still there. Why? If Biff faded away, shouldn't his cane have too? The DeLorean isn't inside a time bubble. It didn't have magical shields. No matter how you look at it, the inconsistency between what happens when one character alters the past and another one does makes no sense. The reason Marty and his siblings were fading was because he was making it so none of them were ever born! He wasn't changing their future... he was eliminating their past. That's not the same thing.

[@rogerwalker2224]

@@Salsuero Yeah its a mindfuck.

[@Tuning_Spork]

@@Salsuero Here's a thought: 2015 Biff handing 1955 Biff the sports almanac doesn't change the timeline at that moment because, at the moment that old Biff left 1955 to return to 2015, young Biff hadn't used the almanac yet. It was only after old Biff had returned to 2015 that young Biff's use of the almanac would cause old Biff to fade away. What I wanna know is why Jennifer, at the end of BTTF3, was asleep on the porch in 1985 (version 2) when Marty and Doc left her on the porch in the erased dystopian Biff World 1985.

[@Salsuero]

@@Tuning_Spork That's not how time works... from 2015's perspective, Biff had already used the almanac for decades prior to 2015 existing. The moment that almanac was in his hands, the future was different because it was - the future. It doesn't "take time" for the future to be changed... because it's already the future - it's already taken time. It wouldn't matter if he returned a microsecond after or a decade after. The reason Jennifer was still there was presumably (not guaranteed) just because they took her back to 1985 and then she became integrated into the space-time continuum at that point, just like everyone else in that 1985... they simply "slid" over into whatever changed timeline resulted from their interactions with the past. She was apparently sleeping there because the changes they made "somehow" had her choosing to sleep there as a probable coincidence. Thing is... you have to come up with justifications for the inconsistencies of logic BECAUSE they are inconsistencies of logic. The likelihood that she'd be asleep on that porch is probably almost zero... but it's not zero. So you just have to go with it. The only way one can time travel into the past is if they first time traveled FROM the past in order to have a tether back to that moment IN the past. However, even if you do that, you have no way of changing anything prior to the moment marked by that tether. And you can't come back from the future to change anything either. It's an anchor... you go forward, you return back, everything you saw will happen because it already did happen. You won't do anything differently because you already did everything differently because you already saw the future in all other possible timelines anyways... you might think you're changing something, but you're not because you had that thought to change something each and every time you thought you changed your thoughts. The future you saw was always the future you saw. There's nothing to change. Everything you do you already did... even if you think you're doing something different. If you saw your own death... you will still die... in exactly the same way... because it already happened... no matter what you think you'll do differently. Everything you do "differently" will still result in that same future. It's not fate or destiny until you know and then it's the same as history - just future history. But, regardless of all that, time travel to ones past is almost certainly impossible unless it's a one-way trip (which is also probably impossible) and you would immediately be living in an alternate timeline indefinitely. There's no fixing anything. Once you do it, it's done.

[@sincman]

The "ever?" was just a bit of foreshadowing of how the relationship between Biff and George would be different going forward but looking at the picture and seeing that all three siblings re-appeared he thought it wouldn't affect things enough to change them.

[@omnipedia-tech]

In Back to the Future 2, I always think about Marty jumping off the top of that building, not looking behind, but just taking a step backwards off the ledge to fall to his apparent death... only to be saved coincidentally at the last second by Doc with the time machine there to catch him. In my mind, what probably happened was Marty actually did die, and what we're seeing on the screen is Doc showing up to rewrite the event.

Instead, he saw what appeared to be Marty Jr. walking to a landed Delorean in 2015, and also overheard their conversation.

[@xenniealsentinel1800]

The tunnel scene tho Biff had to take something from that too That's why 85 triggered him back to bully, which lasted till 15

[@lazyperfectionist1]

I would say that you trivialize the event by describing it as Biff just getting laid _out_ for a little while. The fact is, that event changed the whole _dynamic_ between Biff, George and Lorraine. Being prepared to fight means _hoping_ to win but being prepared to lose. Bullying, on the other hand, means _not_ being prepared to lose. Prior to this event, Biff bullied George _constantly,_ because at every opportunity, he saw what his assessment of the situation gave the appearance of an overwhelming advantage that would discourage George from _any_ kind of opposition. This discouragement disappeared when George saw Biff taking advantage of _Lorraine._ You can see it in the movie. When Biff's treatment of Lorraine pushes her to a state of actual _distress,_ George stops thinking of _himself._ You can tell, he's _not_ thinking, "What's happening to _me_ is wrong. I've got to stand up for _myself."_ He's thinking, "What's happening to _her_ is wrong. I've got to stand up for _her."_ Then, of course, when he lays Biff out, that changes the whole dynamic. For the first time in his entire life, Biff has known _defeat._ For the first time in _his_ entire life, George has known _victory._ Then, when they kiss for the first time, on the dance floor, Lorraine knows she's gonna spend the rest of her life _not_ with a man Biff pushes around, as was the case the first time, but with a man who just discovered he can stand _up_ to Biff when Biff is wrong. That event _transformed_ each character. It showed Biff he _is_ capable of _losing,_ it showed George he _is_ capable of _winning_ and it showed Lorraine that her previous assessments of George were wrong. Each of these changes would have repercussions for the rest of their lives, so don't just call it Biff getting laid _out_ for a little while.

[@Partyboy22]

I totally agree with that assessment. To add to that, it wasn't just Biff Tannen getting laid out by George McFly. It was Biff Tannen getting laid out by George McFly, the "biggest loser at school." George wasn't just picked on and bullied by Biff, he was picked on and bullied by pretty much everyone. So for George to stand up for not so much for himself but for Lorraine and knock him out with one punch, it really dealt a blow to Biff's ego and reputation. It's like a boxer or an MMA fighter getting dominated in a fight and losing. It does something to them psychologically and they may never recover from it. If he tried to intimidate someone afterwards, all the supposed victim had to do was bring up George knocking his ass out and then laugh in his face. At the point, the feared lion becomes a pussycat. Onto George, when that one guy cuts into his and Lorraine's dance, he appears ready to give up and walk away. But then he remembers what happened outside and seeing Lorraine in distress once again. He realized that if he wasn't going to allow Biff to get away with that, he wasn't going to allow this clown to get away it either. It's as if he told himself, "I just laid out the biggest bully at our school. Why should I let this guy walk all over me?" This solidified that confidence from earlier and all of his classmates became aware of it. By knocking out Biff, he went from zero to hero. Lastly, it seems obvious that Lorraine only went out with George to the dance out of pity because her dad hit him with his car. She loved George in the original timeline, but I don't think she ever truly respected him. This is because he never stood up to Biff or anyone, even when the other person did him wrong. So just by going out with him and falling in love with him, George most likely worshipped the ground she walked on. She knew he would never cheat, neglect or abuse her, so he became a safe choice for her. But when he stood up for himself and her at the dance, she no longer felt pity for George. That newfound confidence helped him appear more attractive to her. But you're right. The dynamic from that point on changed for all three.

[@inwalters]

Another overlooked factor is that I think George standing up to Biff encouraged others at the school to do the same. Biff's bullying days were over. After everyone else saw Biff could lose, his power was done and no one was afraid of him anymore. That's why he ended up as a car detailer.

The first theory doesn't make sense. Doc rips up the letter AFTER Marty shows him the photo, so that can't be the moment when he changes his mind. The third theory ... well, sure? That's not even a point someone can argue against. The newspapers change with the events, so why wouldn't the book? The fourth thing is a silly fanfiction. Oh, so Biff is shocked because he sees a flying car that vanishes with fire trails? Who wouldn't be shocked? And many seem to forget that Marty was in 1955 for only a week, met most other people only a handful of times and there are no photographs of him left behind. Why would people 30 years later remember how he looked like, especially when they've seen Marty grow up in the 70s and early 80s? You wouldn't think "oh, that kid I've known for almost two decades now looks like a guy I've seen for a few days 30 years ago: it must be him!"

[@Dargonhuman]

After the segment about Lorraine's trauma and sexual assault by Biff, and the implications it suggests for the "prime" timeline, a really _really_ dark twist would have been to have one of the McFly kids completely disappear after George stands up to Biff - the obvious conclusion being that the missing kid's father wasn't George and leaving the audience to speculate how exactly that particular conception happened.

[@gblargg]

Someone could do an edit that changes the photo scene and cuts out the shots after of the disappeared child.

[@lamontjohnson5810]

While I disagree with the theory that Lorraine was likely assaulted by Biff at the Enchantment Under The Sea Dance in the original 1955, I do think you have an interesting conception. I, for one, love the BTTF movies but I think more should have been changed in the altered 1985 after Marty got his parents back together. His interactions with George in 1955 had a drastic effect on his father's persona and life from that point forward. As a result, it would have been nice to see more dramatic changes to the McFlys or Marty's life when he returned to the altered 1985. The fact that they lived in the same house and his parents had the exact same kids is almost impossible. But I think your concept of having one of Marty's siblings disappear from the photo once Marty fixes things would certainly be a dramatic change worth exploring.

[@gokaury]

These theories are pretty interesting. As for the first one, the only flaw that I see in that theory is that Doc ripped up the note after he had seen Marty's picture restored and Marty's comment that his father had never stood up to Biff before in his life. If Doc had come to the realization that not all future changes are bad, then he would not have ripped up Marty's letter after he discovered it in his pocket. That said, this theory is still totally plausible. Ask for the last theory, I highly very much doubt that Biff is even remotely smart enough to figure that out. I just think that in the 2015 future he was in the right place at the right time.

[@StacieMMeier]

The theory is sound for the last one except for a few issues. First, "Johnny B. Goode", while written in 1955 (The same year Marty was there) was likely already playing it or people assumed it was taken up by another artist. In this cause, Marty has seen it and playing it. This was very common in the 50s as many different versions of the songs exited together. He released the song in 1958, although from what I read, Barry was already playing it at bars and small venues. The second issue, Calvin Klein, The real-life person was born in 1942, and a run of names at that time shows, while rare, there were multi people named this in 1955. So Biff would just assume it was a chance they were named the same. Lastly, it is true, that one person did know who Mary was? His father knew, and he was a Sci-Fi writer, it is likely Marty and him knowing what really happened caused him to become such a good writer. He didn't have to use his mind to write it, he just wrote true to life. EDIT: Skateboarding was becoming a fad by 1955 in California (I admit I had to look this up), so Biff likely knew of them by then. The exact date is uncertain, although one article I read claims it was even possible by the late 40s. Biff being what he was, likely knew of this. Sources: 1. "Written and sung by Berry in 1955, the song is about a semi-literate "country boy" from the New Orleans area, who plays a guitar "just like ringing a bell", and who might one day have his "name in lights". - Taylor, Timothy D. (2000). "Chapter 7 - His Name Was in Lights: Chuck Berry's 'Johnny B. Goode'" 2.

[@drunkdogwithagun468]

I kind of have my own theory about Jennifer as well.

That woman that he married would have been Jennifer’s original mother. Jennifer’s father met a different woman and had a daughter. Let’s say he just wanted to name his first daughter after his grandmother or something like that to say why the name would be consistent. The reason Jennifer looks the same at the end of BtTF1 is kind of like a delayed response from Marty still seeing the original Jennifer where as in BtTF2 we see the new Jennifer because Marty’s mind is catching up to the time travel effects (another effect of Marty’s mind catching up is his attitude change you see from BtTF1->BtTF2) This is my in universe reason why Claudia Wells was replaced Elisabeth Shue.

@@ArgonTheAware The car, because it was hovering, spun on its axis up to the 88 miles per hour, and did so quickly due to both the lighting bolt and the fact it was airborne. That backwards 99 was supposed to signify that. It clearly was poorly done.

@@Reggie2000 The problem with that theory is that in order to get up to 88 MPH it would have to spin more than 250,000 RPM so Doc never would have survived the G-forces produced by it and would end up splattered against the inside of the car

Below is my dark, but plausible, explanation/theory of old Biff’s distressing return to 2015 after giving young Biff the sports almanac. It's a bit long so I appreciate folks taking time to read through it and give their thoughts. There is a deleted scene where Biff returns to 2015, gets out of the Delorean, and proceeds to fade out of existence. If you’ve never seen this you should look up ‘Biff disappears’. I think the creators intended it to be part of the universe they had constructed for BTTF but decided it was too dark for movie goers enjoying a family film, and rightfully so. With that said, despite being ironically "deleted" we should take it to the bank that Biff indeed fades away even though it's not in the final cut. In the first film Marty + siblings fade away when Marty endangers their existence by interfering with George and Lorraine's courtship, so when Biff fades away upon his return to 2015 I believe it's because this same type of interference has occurred in the past with his own ancestors. It could be that when Doc & Marty go back to 1885, THEY are the one's who alter the path of Buford Tannen's life that originally would have resulted in Mad Dog impregnating whatever lucky lady would spawn Biff's ancestors. What we don't see in 1985 after Doc's time machine train disappears is Marty going home and asking his dad "when is Biff coming by to wax the truck" only to have George reply "who?" Marty would then pull out the photograph of Doc Brown’s grave stone, erased towards the end of BTTF 3, to discover it has been replaced with a gravestone for Buford Tannen. I believe Doc Brown, upon rescuing Clara and remaining in 1885, made it a priority to end the Tannen line with Buford regardless of the butterfly effect. Judging by what happens to old Biff upon his return to 2015 I would say that Doc was successful. Like with other instances in these beloved films we forgive some logic that doesn't calculate perfectly and results in an unresolvable paradox due to ripple effects, but given the other general rules (aka guidelines) of the BTTF universe it's plausible. When Biff returns to 2015 he immediately jeopardizes his own existence by #1 giving Doc and Marty a reason to alter his past after giving 1955 Biff the sports almanac and #2 providing Doc and Marty a way to travel into the past via returning the Delorean. The instant the Delorean departs from 2015 with Doc & Marty, Biff's fate is sealed and he disappears. I believe there is actual evidence that this may be at least in-part true. In BTTF 2 as old Biff is in the midst of being erased Doc Brown specifically alludes to his only regret with destroying the time machine being not traveling back to the old west. Interesting timing, no? Regardless of if Doc Brown viciously enacts vengeance, or if the mere event of Buford going to jail alters the future timeline it seems clear to me that Doc Brown & Marty are directly involved in Biff being erased from existence.

[@jaymantisgaming]

in the old VHS box set of the films there was a 4th video which was sort of a Q&A video of common questions about the films. one of the questions was what happens to biff when he comes back? you see him get out of the car in pain and then he disappears (offscreen). its explained that in the timeline where biff is rich, lorraine shoots him after he kills marty. some good points in your theory though

[@pillcosby6817]

Well there were some comics that came put a couple years ago called Biff to the Future which takes place in the Biff timeline what he did with the sports almanac, and what he does to Hill Valley. It's a great read, it throws your theory out the window, I don't want to spoil it

[@markmac2206]

that actually makes sense.

[@jaspermartin7444]

that is really interesting, thank you!

[@RDSports5]

I love the creativity of your theory. For me though, I've always viewed the timelines based on how doc draws them out on the chalkboard in BTTF II when explaining the issues Biff has created and the only way to fix them. Basically, each timeline is it's one dimension, so with that in mind, the 1885 timeline really only comes into effect when Marty arrives back home at the end of Part III, and then changed again when Doc arrives in the Train Time Machine. Prior to that though, what happened in the other timelines is their own individual thing. As others have mentioned about Biff's disappearance, if you look at the FAQs on the VHS or DVD of Part III, the writers pose several theories, one of which being Lorraine shooting Biff sometime in the past (of his own twisted timeline), and the Ripple Effect eventually catching up and causing Old Biff to disappear from existence. He could've also died from the shock of time travel itself and his age, although this is more of a boring theory to me. And finally, I think Old Biff had died by some other means in his own timeline, and so therefore cannot exist in his version of 2015. The most fun and plausible theory though is that Lorraine shot him at some point in his timeline, that makes the most sense to me

[@danb9277]

One thing that always made me wonder is "What was the point of Back to the Future 2?" The premise of the movie was Doc went to the future then brought Marty there to do something about his kids. If Doc's plan went off without a hitch: Marty tells Griff "No", his son doesn't go to jail, and it doesn't ruin his family. They go back to the past. But, why? That future is now "reset" once he goes back to 1985. What was the point of going to the future anyway? Because of the events that happen once the plan goes awry, Jennifer finds out that Marty was in a wreck with a Rolls Royce that ruined his life, and losing his job because he let his temper get the better of him. The events of II and III lead Marty to realize he needs to stop being a hothead and getting goaded into trouble. The problem with this is, how would he come to this realization by just helping his son in the future? Was he supposed to learn this from that incident?

[@shinjisan2015]

The intention of Doc helping Marty Jr in the future had nothing to do with Marty having a realisation about his own life, literally just that one favour for a friend. Doc had no family himself, so why not look into the family of Marty in the future? Heck, Marty even told him to look him up in the future before Doc drove away at the end of 1. Doc was trying to do the "bulletproof vest" approach. One small change to do a favour for his friend's family in the future. He says Marty turns out fine, which really he pretty much does, just okay but not awesome like he hoped. The change revolved around a Tanner, so something about that family just gets under the skin of Doc. A whole family of bullies. There was a great post pointing out that Marty changed between 1 and 2, because his parents were different. He grew up more hotheaded and sure of himself "nobody calls me chicken".

[@justinwilliams1127]

I see it as trying to give advice to someone who doesn't want it, like someone in love with someone that is bad for them. You can reason with them all you'd like, but they will never enact change until they see the reasoning as well. You can tell Marty all day not to race or be a hot-head, but it does little good if he doesn't see why it's a problem. By witnessing the effects of his behavior upon his friends and family, Marty is finally able to come to terms with what he needs to learn as an adult. Is that why they made II and III? Nope. Money is the reason, but if we are to TRY and rationalize the story, that's my theory on the point of these movies for the character of Marty.

[@jacobarnold3623]

When Marty shows Doc the picture of him and his siblings for the first time trying to prove he was the future you can already see his brothers hair is disappearing

I've always wondered about the mall sign at the end of the first movie. To the Marty we follow it reads "lone Pine" but what if the past Marty looks up at it from the parking lot, it would still read "twin pines". So the sign would be both versions at the same time, maybe there are infinite versions of it and what it reads depends on who is looking at it.

[@drewlovelyhell4892]

No, the other Marty was born in and grew up in the new timeline, so it would have always been Lone Pine to him. Marty is the only one who knows it used to be Twin Pines.

[@vintagevideogamenights2923]

The theory about the Almanac is the only one that sustains itself. The movie shows that information gets corrected when the past changes, like with the headline "Doc Brown committed/ commanded", the Clayton/Eastwood ravine or the Twin Pines/ Lone Pine Mall. The one about Biff is completely ludicrous. The Enchantment Under the Sea is their highschool graduation, meaning those people would move on with their lives and Bifff would have to face reality, that he is someone without skills, brain or money to succeed in life, so getting stuck in a car detailing job is just natural progression. The one about Lorraine ignores that Biff went to the parking lot after Marty (Calvin) for revenge, after all, he "wrecked" his car. Once there, he saw Lorraine and decided to attack her. There was no motivation for Biff to be there in the original timeline and attack Lorraine. The difference in Lorraine's personality is explained by the influence of whom she falls in love with: a loser in the original timeline and a winner in the altered one. George had the influence to drag her down or lift her up, not Biff. About Doc Brown's expression, he is just thinking "oh sh!t, Marty changed history". Doc Brown explicitly said to Marty not alter any past events as the changes could be catastrophic. When Marty proudly announces that his father changed himself, Doc Brown realizes that his attempt to not change the future failed.

That last one is stretching. What’s more likely is that in the original timeline he has always pushed George around to the point where George got him a job at his company, then Biff basically bullied information out of George in order to steal what career George may have got at that company (George is doing Biffs reports, and going by the way they are dressed it looks like Biff is his superior, a job that George would have if Biff wasn’t around). After George stands up to him in the alternate timeline, Biff no longer bullies George and doesn’t get the job, and like you said he has no real prospects in terms of education so ends up doing manual work for the rest of his life. He just happens to be washing the McFly’s cars at the end of the film purely to show what happened to him later in life. Why else would he have that look on his face and say “what is going on here” if he knew what was going on there? Also it’s clear he only figures it out in part 2 when he says “so.. doc Brown invented a time machine”. Where as he would say something like “so.. doc brown was the one who invented a time machine”.

One other theory I have heard thrown around was that by the end of the 3rd film Biff has it figured out and while working on Marty's truck he messed with Marty's brakes in a way that would cause them to fail under hard braking causing him to crash into the Rolls-Royce and subsequently ruined his life

[@terriquinlan7683]

I need a theory to explain how and even why George originally got Lorraine to go to the dance with him. ??? It wasn't like he gave any hint that he wanted to. He was engrossed in his stories, and was perfectly aware of Biff's determined interest in Lorraine, which was a massive deterrent. Marty pestered him until he asked her to go. (Or, he was scared of what Lord Vader would do to him.) So Lorraine felt sorry for him after dad hit him with the car. That explains her interest in him (dubiously). It doesn't provide an explanation of why he asked her. So....hit me. Was it something she did when he came to in her bedroom?

If only Marty could have convinced Lorraine to knock him out instead, and made sure she had a nice wrench handy to do it with...

[@zandelscomicsandcards7543]

I agree with all the theories except the last one. Biff became timid because he was afraid of George cause George was the only one to ever stand up to him and fight back. To everyone else he was still a bossy jerk and a bully. Everyone except George. He’s scared of George cause he knows George will stand up to him and humiliate him.

[@davechan8613]

I like another dark theory that I heard elsewhere, where Doc was depressed, had lost everything and this time machine was all he had left. If it didn’t work, there’d be no point in going on. So he and Marty stood in the way of the Delorian in a last ditch effort/suicide attempt. If the time machine didn’t work, the car would run them over. Doc also didn’t want to die alone, so he brought Marty there to record their time travel attempt/suicide. He was so surprised that it had actually worked, as he was used to a lifetime of failure.

[@stickyfingers5189]

The almanac theory is solid, though it does bring up one question - why isn't the DeLorean effected the same way? Sure, its not filled with information the same way - but it would have been effected in design by changes to the timeline. Subtle things like a manufacturing law being slightly different (you can find plenty of examples of 'odd looking' cars designed around said laws regarding things like maximum height of headlights and the shape of front bumpers) or a designer not getting the same inspiration during concept creation.

[@erikziak1249]

What always bothered me. Clara Clayton. Clayton ravine. In the second move, we see the gravestone of Doc, with Clara and both Marty and Doc wonder who she might be. Then, in the third movie, Doc is being asked to pick Clara at the train station, but Marty interferes with this and they both go out to examine the unfinished rail track. It is there, and only with Marty interfering, that Doc actually saves Clara. Without Marty getting back in time, Clara would have never arrived at Hill Valley, as she would be dead in the ravine. So, the gravestone makes no sense, because Marty did not travel back in time yet. In the movie, it might have been simply resolved by Doc saying something like "Oh yes, that is a nice spot, I go there often, just get my head out of town now and then". This would give a reasonable possibility, that Doc would have been out there, saving Clara, even in case Marty never traveled back in time. As said, this detail always bothered me from the very first time I saw the third movie. I do not know if it was put there intentionally to mess with people, or it was a mistake.

[@chriss4084]

I think its a ripple effect from Marty changing the original timeline in the first movie. Just as his parents changed everything changed slightly. At that point marty and doc exist in a new timeline with a working time machine and are part of a loop. Doc met Claira because it happend already in the post bttf1 timeline and marty causing him to meet her was already in motion. We never get to see what happens in the current 1985 and the ripple of marty saving doc as the movie ends just after he returns.

[@WilshireD]

There are actually 3 different timelines in play that account for this. Timeline 1: Neither Marty nor Doc go back to 1885. No one is there to pick up Clara from the train station. She takes a carriage by herself and falls in the ravine. This is the scenario Marty remembers when he recalls the name of the ravine as Clayton Ravine. Had Marty visited the ravine after Doc traveled to 1885, he would have seen it called something else, but he just assumed it was the same. Scenario 2: Only Doc goes back to 1885. He still gets asked to pick up Clara from the train station, but not realizing her original fate or their future relationship, he does end up picking her up, preventing the events leading to her falling into the ravine from unfolding. They fall in love, which leads to her being mentioned on his gravestone after he gets killed by Buford Tannen. Scenario 3: both Marty and Doc travel back to 1885, which leads to the events seen in the movie. Even though Doc is still asked to pick up Clara from the train station, he becomes aware of their future relationship beforehand due to Marty showing him the photo of his gravestone. He decides to not pick her up at the train station to avoid meeting her, but does not realize he would still meet her and save her right before she falls in the ravine.

[@erikziak1249]

@@WilshireD The train station is displayed as being close to the city, practically in the center. Why should Clara take any carriage for the short trip?

The Biff theory has 1 big problem, Biff wasn't that smart. In fact he was basically an idiot & it was all his fault. He probably cheated his way through school. We see in the 1st diner scene he had George do hi homework. He probably had not only George, but several other kids do his work for him. He probably found smart kids he could intimidate to do his homework in various subjects. As an adult in the original timeline he did the same to George & his coworkers. This only worked because he could intimate his peers. However, this all changed after George laid him out easily with 1 punch not even breaking a sweat; made worse by the fact that George was literally at his mercy less than a second before. Remember George was literally the town wimp!! Once word got around town what happened nobody would be afraid of him anymore. This could easily turn him into the man we see at the end of the movie. I know he was the same in part 2, but it'd take time for the word to spread around the whole town. Finally, Biff can't be called a complete loser. After all he runs his own business which is still in operation to at least 2015. It takes some smarts to start & run a business even if it's barely staying a float. Also, seeing how 2015 Biff seems to be doing moderately well means he's doing well. Also, since he seems to have a habit of trying to short change people, but they still hire him must mean h does a pretty good job. My only problem is how in part 2 he was able to operate the DeLorean. I can accept him knowing how to drive it & Mr. Fusion, but how did he figure out the time controls. Finally, I know he went back to being a jerk in 2015, but something could of happened between 1985 & 2015, which we didn't see or we do see him only acting like that with Marty Jr., who acted like his Grandpa at that age, He could just be acting like a big shot bullying people who were weaker. After all hi attitude changes when Griff enters, before that there was literally just Marty Jr. & 2 little kids hanging around the staff weren't even on the floor.

[@rogerwalker2224]

[@mnomic8371]

There is one major flaw in BTTF 2. If in 2015, Biff took the Sports Almanac from the dustbin, stole the DeLorian, then travelled back to 1955 to give the Almanac to his younger self. Then how did he travel back to the future to the same 2015 where he had just been? Giving the younger Biff the Almanac would have set in motion the series of winning streaks that would have made Biff a millionaire and the events that led to what we see later (the bad version on 1985). If the old Biff stole the DeLorian then he would’ve returned to a very different and bad version of 2015. Even Doc explains this later on when they go back to 1985 and everything is messed up. The old Biff would have changed the timeline as he had control of the time machine.

[@PoliceTelephoneBox]

Time was still in flux, as long as there a way for the timeline to stay the same, the future wouldn't have changed yet, it's only when that change is permanent that the new timeline takes over. It's why in the 1st movie Marty has a chance to fix things, instead of vanishing immediately. In this case, Old Biff left before young Biff started making bets, so he went to the original future. But as others mentioned, in a deleted scene he disappears after Doc and Marty leave to go to the now alternate 1985. For them the change happened as they were time traveling, so they weren't affected.

[@mnomic8371]

@@PoliceTelephoneBox Thanks for the thorough explanation 👍🏻 Yes I get what you mean; I suppose if you were in Marty & Doc’s perspective then from their viewpoint they were still in 2015 when Old Biff went back to change things. So the timeline couldn’t change whilst Marty and Doc where still in 2015. But as soon as they moved from that time to the past, things all started to unfold from 1955 to 1985, where young Biff starts winning bets and turning the place into a shithole 😉

[@JMoviesMedia]

1) I thought it was just assumed that Doc figured out that there was good changes that also occurre because he obviously said, "Well, I thought... what the hell?" after reading the letter and putting on a bullet proof vest and saving his life. 2) Again I thought it was assumed that Loraine was depressed and unhappy as per the evidence of her drinking. I do however find the irony fascinating. If Loraine isn't happy with a jerk, assertive person like Biff nor a wimp and soft person like George then it says like Loraine it's very hard to make a woman happy, yet it's sort of easy at the same time. You just have to be a confident, assertive and yet sensitive and caring person to hit the right spot in a woman's heart. Or better put by Troy in Blast from the Past, "You're a nice boy but what Eve needs is a nice man." 3) I think it's true the Almanac like books, media etc can change. However, I don't think this theory has to be given being how unrelevemt it is to the story we're dealing with. Marty wouldn't have ever thought of or need to sabotage any races. The only changes that might occur is a football game changing because George, Loraine, Biff, Marty or possibly a 3rd party effected by the charges being somewhere they shouldn't be and injuring or effecting one of the players unintentionally thus changing the game. But still very unlikely. 4) I highly doubt Biff knows anything, after all he's a "butthead". If he can't even notice the two different Marty's at the moment the door opens then he doesn't have the knowledge to catch anything more deep. Just saying. Plus Biff would obviously try to pass that job on to a P.I. like he does everyone else. So look out for the P.I. not Biff. Lol.

If the theory is true, it was the sexual assault that led her to drink and be damaged. Having lame George as a husband probably made her sad, too.

[@JMoviesMedia]

@@davidm4566 That's what I allude to. I think the evidence says it wasn't merely the event so much it was being with someone like old George who couldn't protect her. As I said, I'm more interested in the irony of the whole aspect of her being unhappy in both cases until George is set right.

The future in part 2 (the dystopian Hill Valley) is Doc's fault. He threw out the almanac, allowing Biff to find it. The alternate future was Doc's fault but he makes Marty seem like the bad guy.

[@LainK1978]

Because Marty initiated it by buying the Almanac even though he was fully aware of how malleable the future is.

[@markmac2206]

or its Doc's fault for inventing time travel in the first place.

[@centurion8446]

Interesting stuff. Especially the last one when considering the deleted scene of old Biff dissapearing out of existence after he got back

[@alvexok5523]

Wow, this is a very well thought out video. Every idea is explained so well and makes so much sense

[@taitano12]

The Lorraine's Past part had me almost crying. Rape is one of those things that can ruin a person. I've seen what it can do. Some can survive and move on. Most survive but carry the weight with them. Some... For some, they died when it happened. Though they still walk, they're not at all who they were; they're a living ghost of what was.

[@billnotice9957]

Maybe? Sometimes one bad event leads to another. Since Biff was humbled by George McFly other people bullied stood up to Biff too! Rarely do rapist strike once and be done. He might to been nabbed by law enforcement and sent to prison, or forced to join the Army for other attempted rapes. He might to been beaten so badly by a someone because of his behavior it shattered hiss ego. I remember one of coolest cats in High School. I meet him at 30 and he was a shell of what he was. Biff might of been him. Some people's High School days are their crowning achievement in life. ( Al Bundy's 4 touchdowns! )Yes Old Biff connected the dots. I am sure the image of the DeLorean time warping stayed with him. He rallied to not necessary to screw Marty or get revenge when he stole the DeLorean. I am sure he only intended to IMPROVE his life only. Why else would he return with it to the future. In his mind Biff thought he could park back where he found it and nobody would be the wiser!

[@LainK1978]

I would bet it probably had more to do with him actually recognizing Doc Brown, than him recognizing the DeLorean itself. Doc Brown was mid 30s in 1955, was mid 60s in 1985, and would have been mid 90s in 2015. It is more likely than not that he would have died before that, perhaps recently and Biff seeing a very young Doc Brown put something together combined with the talk between Doc and Marty.

[@billnotice9957]

@@LainK1978 Fair points. But Biff strikes me as person not very bright. I do not recall Biff having any interaction with Doc brown in 1955.

[@billnotice9957]

Agreed. But a warping flying car is a novelty nobody would forget. Biff is clearly a hand to mouth thinker with ZERO experience time traveling.

Damn, you took this to another level! Getting my sub for sure. Great job

[@wildcaveman5310]

I don’t buy the claim that biff had the patience to undergo a multi-decade long undercover investigation. It doesn’t fit his character. After he sees the flying vanishing car his actions through to the future does fit this idea though.

[@riparianlife97701]

That last one was absolutely solid.

[@JAGtheTrekkieGEMINI1701]

Every theory Sounds reasonable except the Last one regarding Biff

[@MrGigaHurtz]

7:58 I don't think that would have worked either because the almanac would have changed in the past too and Biif's bet would have changed. The only way would be to find the almanac writer and convince them to put false information for the specific things Biff bet on to deter him.

[@rus0004]

I love how most time machines don't take movement through space into account. The Earth moves through space at up to around 540 miles per second (nearly 2 million miles per hour). To move just one year through time would mean your point of origin would have moved over 17 Billion miles out from under you, and you and your DeLorean are effectively banished to the vast nothingness of the void.

[@rogerwalker2224]

I considered this when trying to write my own time traveling story. The character would end up far, far away and take lifetimes to return to Earth and it would become infeasible, or impractical to time travel. So the solution is to just assume the time machine can adjust for the movement of spacetime.

[@the_kombinator]

Hah my dad explained this to me when I was like 8 and we saw the movie together. He hoped that the car had its own supply of oxygen and was spaceworthy.

[@futuramayeah]

i remember thinking of this and realizing that to have a time machine? it has to be? a spaceship like in Legends of Tomorrow the tv show from the CW. but didn't Tesla accidentally make a time machine in one of his labs , on the ground on Earth?

[@xaosbob]

Two words: gravity well. Since we're dealing with what is (currently) basically magic-level science anyway, offsetting spatial coordinates to account for the movement of the planet would be simple. Even simpler from a relativistic standpoint if you account for Earth's gravity well in those calculations.
