Continuity mistake: As Max and Jude are talking within the maintenance room, Max is seen taking cigarettes out of his pocket as he sits on the bed. When they change angles, Max is seen pulling the same cigarettes out of his pocket. (00:17:00)
Continuity mistake: After Jude and Max move to New York, the scene switches to some girls riding bikes through a suburb. A girl in the background of the shot is jump roping backwards, but when the camera cuts to a different angle, she is jumping rope forwards. (00:32:40)
Factual error: After Jude gets arrested and comes back to Liverpool the shot of him walking across a bridge shows a train in the background. The train network in Liverpool wasn't established until the 1970's, and regardless, the train shown is a modern train which started to be used in about 2005. (01:47:00)
Continuity mistake: Near the end, when Lucy tries to get into the building, she is blocked by police officers holding clubs straight ahead in front of them. The scene cuts to a roof shot, then back again, and Lucy tries again, but the clubs are missing, the cops just have their hands out in front of them.
Revealing mistake: Although set in the 1960's, the school bus lettering was Arial, a font not invented until 1983.
Continuity mistake: During "Hey Jude" when the drummer drums on the cans the wall in front of him is not hit by the sun or showing any light, almost as if he is in a large ally. But after he kicks the lid off the can and the scene changes there is a ray of light on the whole wall.
Factual error: Although set in the 1960's, a modern UPS truck is seen just before the rooftop concert scene.
Other mistake: During the "Come Together" sequence when all of the business men have their big dance number, if you look to the right closely, one of the business men trips.
Continuity mistake: During "With a Little Help from My Friends", the group appear to be passing a joint between themselves. If you look closely, you can see they aren't even holding anything, even though Jude coughs out smoke during the scene.
