Continuity mistake: There is a scene in the movie where the Beatles enter a limousine, I believe at the beginning of the movie. In this particular scene the Beatles are all dressed in suits and ties, but when the Beatles are filmed in the limo, John Lennon is wearing a turtle neck sweater beneath a blazer.
Continuity mistake: While looking for the canteen, George inadvertently wanders into a production office. The receptionist takes George in to see Simon, who believes George is there to audition for a testimonial for those "dead grotty" shirts. While the receptionist is sitting on Simon's desk, her legs are straight. After Simon says, "Because he isn't wearing one of these nasty things", her legs are instantly crossed. (00:43:50)
Continuity mistake: As Paul runs out of the train to his awaiting limo its door is open. In the next shot we see him from a different angle and he opens the door again. (00:16:20)
Other mistake: When Ringo and the young boy with the tire walk along the path together and the boy asks Ringo, "Why aren't you at work?," you can see Ringo mouthing the line along with him.
Continuity mistake: When Paul's grandfather goes to the queue of girl's waiting to see the Beatles, he offers free autographed pictures. As he is mobbed he yells "Oh me bum....me hat.". We see his hat has been taken/knocked off as some bobbies come to break it up. A quick cut to a different angle and grandpa's hat is back on his head. (01:06:30)
Continuity mistake: John asks Paul's grandfather, "Are you nursing a broken heart?" and if you look over his head the window is closed. No one goes near it but two shots later John stands up and walks over to the old man and the window is now open. (00:04:10 - 00:06:35)
Continuity mistake: When the boys sneak off to the nightclub, the clothes they are wearing when they leave the hotel are different from those that they are wearing for the remainder of the night.
Other mistake: When the Beatles are playing cards and singing "I Should Have Known Better," Paul (who shouldn't really be singing anyway) flubs the first line of the last verse. He sings "I sh... [laughs] never realized..." John does almost the exact same thing when they sing "I Should Have Known Better" in the concert scene.
Visible crew/equipment: In the opening credits two cameramen are seen in the reflection of the window. (00:01:00)
Continuity mistake: As The Beatles go out to the field while "Can't buy me love" is playing Ringo has his camera. It disappears after they come down the fire escape and doesn't return for the rest of the scene. (00:37:50 - 00:39:35)
Continuity mistake: When Ringo looks in the mirror in the hotel room he has a peeled banana in his hand, then in the next scene it disappears. (00:17:50)
Continuity mistake: As The Beatles leave the train Paul goes through the first limo and we can see the second limo he's running to with a bunch of photographers standing at the side of it taking pictures. In the next shot the photographers are standing in front of the car and not taking any pictures. (00:16:25)
Continuity mistake: When the Beatles run out into the field it's an overcast day. In the very next scene the sun is shining. (00:37:50)
Visible crew/equipment: In their final performance look closely and you can see director Richard Lester moving through the shot. He's between the Beatles and the audience. (01:16:30)
Visible crew/equipment: In the dining car the reflection of the crew and the equipment can be seen on the far right against the wall. (00:08:15)
Other mistake: When the Beatles are rehearsing for the TV gig, it is easy to see that they are not actually playing their instruments. John points out to Ringo that he isn't even hitting the cymbals, which he attempts to improve.
Continuity mistake: Paul's Grandfather has a wide grin on his face when Norm walks into their car on the train. In the very next shot it's gone. (00:05:00)
Continuity mistake: Paul combs his hair in the mirror during the train sequence. After that a lock of hair appears over his left eyebrow for several shots. By the end of the scene his hair is back to being combed perfectly. (00:04:30)
Visible crew/equipment: On the train you can see a shadow of a mike on John's chin when he says, "No that's his other one." (00:04:50)
Continuity mistake: In several shots of the audience, girls can be seen sitting in seats, then several shots later they've moved and can be seen leaning over the balcony. (01:21:55 - 01:22:50)
