At Disney's Hollywood Studios at Walt Disney World, where Mickey and Minnie's Runaway Railway is now. This is one scene in a really long ride, which goes through all sorts of movie environments and actually involves live actors as well as animatronics. There's a sort of tour guide riding on the vehicle with you, but then it gets "hijacked" by either a Wild West outlaw or a movie gangster, another actor who is on the ride vehicle at this point, a bit baffled by the science-fiction trappings. Then the miscreant attempts to steal an artifact in the Indy scene and is stopped by a mysterious figure who turns out to be your guide again.
