Audio problem: During the final concert, Ringo's drumming is frequently out of sync with the sounds heard.
Audio problem: In the back of the train as his grandfather sits locked up Paul says, "Well you've got to admit you've upset a lot of people," and Paul's voice sounds natural. His voice in the next line sounds entirely different as he says, "At least I can keep my eye on you while you're stuck in here," and is an obvious over-dub done in another place. (00:13:15)
Continuity mistake: In the lunch car as Paul signs the picture for his grandfather he's holding it with his right hand. In the next shot his hand has moved and he's holding in with his thumb. (00:09:10)
Continuity mistake: When John says to Paul's grandfather, "Ya see you know what your trouble is, you should have gone West to America," they're standing about six feet apart, but in the next shot John has his arm on his shoulder. (01:14:30)
Continuity mistake: The opening for the elevator where Paul's grandfather pops up through the stage floor disappears between shots at the end of "She Loves You". (01:24:05)
Continuity mistake: George goes into a TV producers office and the secretary's phone is pushed right up against the edge of her desk. In the next shot when she puts on her shoe the phone is pushed back about two inches from the edge of the desk. (00:41:40)
Continuity mistake: As The Beatles leave their hotel room, in the corner on a left is a guitar case, a vase, and a bottle of Pepsi underneath the mirror. When they come back the bottle of Pepsi is gone. (00:19:00 - 00:24:35)
Factual error: When they sing "I Should Have Known Better" look at Paul's left wrist - he's wearing a metal ID bracelet. Anyone who plays guitar knows that they jangle against the strings. He makes sure in any real live performances that it is tucked up in his sleeve away from the strings. (00:13:40 - 00:34:20)
Continuity mistake: The makeup on the boy that Ringo meets keeps changing.
Revealing mistake: John takes a pair of scissors and cuts the tailor's tape measure as he says, "I now declare this bridge open". Everyone else has left the room but the tailor winks at someone off camera. (00:47:10)
