Continuity mistake: As he talks to Norm, Shake the TV producer says, " If they don't show up I wouldn't be in your shoes for all the tea in China" and the clock above his head reads 7:12 PM. In the next shot we see Paul's grandfather trying to sell autographed pictures of The Beatles to the girls on line outside the theater and it's mid-afternoon. (01:05:25)
Continuity mistake: When Paul's grandfather pulls the elevator lever he throws the pictures down in a messy pile. In the next shot when he pops up on stage the pictures are in a neat pile. (00:46:05)
Continuity mistake: When Ringo goes out "parading" two girls recognize him as he walks down the street taking pictures with his camera. If you look closely the cars parked on the street to the right of the screen change between shots. (01:01:10)
Continuity mistake: On the train we never see Shake hand anything to John then all of a sudden, he has a Pepsi and his hand. (00:04:40)
Audio problem: When Ringo turns on the transistor radio, he plays with the volume control, but the sound on the radio doesn't change until after he lifts his finger. (00:07:00)
Continuity mistake: Wilfrid Brambell asks Paul to sign a Beatle picture and he uses a ballpoint pen. Later, he copies them over using the master copy that The Beatles signed with ballpoint pens. Their signatures are now different (done with a thick felt marker) so they can stand out better in the black and white shot. (00:09:10 - 00:45:50)
Continuity mistake: When the TV producer says to George "of course they're grotty, you wretched nit" his hands are out in front of him. In the previous shot his hands were behind his back. (00:43:50)
Continuity mistake: Ringo hangs out in a bar and accidentally ruins a game that two guys are playing as he spills some change from his coat onto their board. The coins are rearranged on the board between shots. (01:04:05)
Continuity mistake: In final performance sequence watch for Ringo's mysterious moving bongo drums. They're on his right and disappear, then reappear, disappear and then reappear several times. (01:22:45 - 01:24:05)
Continuity mistake: When George is showing Shake how to shave in the hotel bathroom, he puts shaving cream on the mirror. In the next shot the bathroom door opens, Norm enters and the mirror is completely clean.
Continuity mistake: Watch the clock on a wall. Six minutes of the movie go by but that clock hasn't moved one minute. (00:39:50 - 00:46:25)
Suggested correction: The clock could be broken.
This is pure speculation, not a valid correction.
While it's possible the correction was done without viewing the scene/movie, a clock not moving (or showing the wrong time) isn't a valid mistake unless the same clock is shown working in the scene. The original mistake does not indicate the clock is working or that the time changes.
Audio problem: During the show George stops playing as he yanks Paul's grandfather off the stage but we still hear his lead guitar riff in "She Loves You". (01:23:20)
Audio problem: A studio engineer tries to play with Ringo's drums and George says, "He's very fussy about his drums. They loom large in his legend," as he tries to tune his guitar. If you listen closely George is paying his fifth string while adjusting the tuning peg of his fourth string on his Rickenbacker. (00:32:25)
Other mistake: An old woman in a dress shop peeps out to see all the cameras in front of her store before the Beatles run by on their way back to the studio. (01:13:40)
Continuity mistake: In this scene George passes a poster that reads "Hughes and Macready". Two shots later it's back in a different place place. (00:42:10)
Continuity mistake: After "She Loves You" they bow and the sign behind them is lit up and says "Beatles". The editor made a mistake here and inserted a shot from earlier in the movie with the stage background from the song "Tell Me Why". (01:24:25)
Audio problem: When Ringo is "parading" he comes out of a thrift shop wearing his new over coat and hat and tries to talk to a girl in a black jacket. We hear her say to him, "Get out of it, Shorty" but her lips are saying something entirely different. (01:00:40)
Continuity mistake: When Paul's grandfather is below the stage the pictures are on his left. As he emerges on the stage the pictures are now on his right. (00:46:00)
Continuity mistake: The clock on the wall is constantly changing time in this scene. You can see it several times and you can see its reflection in the mirror. (00:47:00)
Continuity mistake: Upon their return the TV producer says to The Beatles, " You don't know what this means to me, if you hadn't come back it would have meant The Epilogue or News in Welsh" as they get ready for the show. Norm is standing behind the producer but then in the next shot as he talks to him he's on his right. (01:14:00)
