Visible crew/equipment: In the opening credits two cameramen are seen in the reflection of the window. (00:01:00)
Continuity mistake: In the intro credits, John, George and Ringo jump onto several stacks of newspapers and John is sitting on them to the right. In the next shot he is crouching with both hands in front him ready to jump off. (00:01:25)
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: 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)
Continuity mistake: Shake has only one Pepsi which he gives to George, then later there are two. (00:03:35 - 00:05:05)
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: 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: 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)
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)
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: 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)
Visible crew/equipment: Someone's shadow goes across Ringo's face while he's taking a picture in their train car. (00:05:10)
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)
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)
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)
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: 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: 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)
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)
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)
