And then there's this one:The name of the band is actually never uttered in the film. It's seen, in a drum logo and elsewhere, but in the dialogue, they are only "the boys," as if the filmmakers intended them to be Everybeatles.
The fans in the movie are all carefully controlled extras — except in one train shot at the beginning of the movie. For the most part, the production managed to stay a step ahead of hysterical Beatlemaniacs, but they somehow found out about the train station location on the first day of filming. Although it's shot from far enough away that you might think there are stand-ins for the Beatles, they really were chased onto that train, and Lester himself grabbed a camera to capture the unplanned moment. He remembered members of the band being furious, thinking security would be that lax for the entire shoot.
During which George ACTUALLY FALLS DOWN ON THE CONCRETE AND MERELY GETS BACK UP!!
