Continuity mistake: When they sing "Tell Me Why" for the TV show there's a shot taken from behind The Beatles. Here as John sings, "Well I'm beggin' on my bended knees" the microphone that was in front of him has now been moved and is facing Ringo. Later in the scene you can see that there are only two microphones on the stage here, one for Paul and George and one for John. (01:16:25 - 01:18:45)
Revealing mistake: In their hotel room Ringo says, "Do I snore, John?" If you look at Paul's hands on the piano it's obvious that he's not playing and that it's an over-dub that we are listening to. (00:17:30)
Continuity mistake: In all the overhead helicopter shots the shadows are very long. The shots on the ground have less of a shadow indicating they were done several hours later. (00:37:50 - 00:38:45)
Continuity mistake: The stage lift that Paul's grandfather is sitting on while signing the pictures is larger, and a different color that the stage lift he comes up on in the middle of the play. (00:45:45)
Continuity mistake: The TV producer talks to George and says, "I mean lines ducky, can you handle lines?" and his two assistants are sitting on the window sill in front of the blinds. In the next shot they both have moved over about four feet to their left and are not in front of the window anymore. (00:43:10)
Continuity mistake: When The Beatles first enter their stateroom on the train we see the door as Paul opens it and there's a first-class sign on it. Later Norm and Shake leave the stateroom as the older grumpy gentleman walks in. They never leave but this stateroom is not the same one that The Beatles walked into before as it has another sticker under the first-class sign that reads, "All Seats Reserved". (00:02:55 - 00:06:00)
Visible crew/equipment: A grumpy old man comes into their stateroom and sits with The Beatles. If you watch closely on the left of the screen someone bumps into the stage light and we can see it flicker. (00:06:05)
Visible crew/equipment: In their final performance Richard Lester's shadow is seen going across John Lennon's back as he walks from the back of the stage to the spot where we see him between The Beatles and the audience. (01:16:30)
Continuity mistake: Sitting at their table Paul's grandfather tries to convince Ringo to stop reading his book and if you look closely there's plenty of sugar in the sugar shaker. No one touches it but when the old man says, "So you are a man after all" the sugar shaker is all of a sudden empty. (00:57:00)
Visible crew/equipment: Someone's shadow goes across Ringo's face while he's taking a picture in their train car. (00:05:10)
Plot hole: When the boys go to get Ringo out of the police station, the other 3 are in front of the police officers and Ringo is way behind strolling along with his camera. When they get trapped in the courtyard they are all together. How did Ringo manage to pass all the policemen with out getting arrested, whilst going slower than everyone else?
Factual error: They're meant to be taping a TV show, but some of the cameras were motion picture cameras used for shooting the movie, rather than TV cameras. (01:16:45)
Continuity mistake: At the very end of "I Should Have Known Better" all The Beatles' microphones have been removed from in front of them. (01:21:15)
Continuity mistake: In the commissary Paul's grandfather says, "Would'ya look at 'em" as he tries to get Ringo to stop reading his book, which he holds differently between shots. (00:56:35)
Continuity mistake: As The Beatles sit in the train car talking about Paul's grandfather Paul says, "he's nursing a broken heart" and Paul is sitting behind his grandfather. In the next shot he's leaning in front of him. (00:03:45)
Continuity mistake: Sitting in the lunch car Norm gives Paul's grandfather the pictures and the old man says, "Hey Paulie would you sign one of them for us" as he puts the pictures on his plate. In the next shot the plate is not there. (00:09:05)
Continuity mistake: As the boys leave in the helicopter at the end of the film, it says "BEATLES" on the aircraft's door. The name is split into two different sections to fit on the sliding panels. A few seconds later, one half of the name is missing, leaving only "BEA" on the left-hand side.
Audio problem: As George sings, "I'm happy just to dance with you" four girls stand next to Paul and Ringo as their boss comes out yelling at them to get back to work. If you look at Ringo, his drumming is in perfect sync with the song but Paul's bass playing is not. (00:54:35)
Visible crew/equipment: The cameraman's shadow and reflection are seen on the left of the photo booth that the Beatles were hiding in during the opening scenes. (00:02:00)
Continuity mistake: Shake has only one Pepsi which he gives to George, then later there are two. (00:03:35 - 00:05:05)
Chosen answer: John is just messing with her. She recognizes him as being one of the famous Beatles, but he tells her that he's "not" John Lennon, to which she responds that "you look just like him." He finally convinces her that he is not John Lennon, and she tells him, "Actually, you don't look like him at all," to which the now insulted John puts on his hat and leaves.
