Hard Day's Night (1964)

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.

John: Control yourself. You'll spurt.

Trivia: During one of the songs, Shake brings an amp onto the set. Watch as George proceeds to knock it over seconds later.
