I just watched this movie and it was really enjoyable and very likable. Is too bad nobody asked in this question and answer about the two elderly people in the theater that didn’t run out and thought it was part of the theater experience? Were they deliberate, extras or actors in costumes speaking Mandarin or something or just happen to be in the area and we’re willing to do a simple scene? Also, with all the background vehicles and people in the city where they 100% movie extras are mixed in with the general public or did they have any idea there was a movie going on or both?
