Help! (1965)

Continuity mistake: The scene where the wheel falls off the car is obviously not the first take as the bottom edge of the rear wing is already damaged from where it hits the ground. It wasn't damaged in the previous shot, when George is undoing the wheel nuts.

Ahme: Hold! Release him or I shoot, and I am a dead-eye shot, shooting.

Trivia: When the scenes in the Alps were filmed, a large group of photographers followed the Beatles around, determined to get a photo of one falling off their skis. The only one they actualy got was staged by Paul.
