Plot hole: When the albino kidnaps Gloria in the middle of the day, he is looking for the film obviously. So he would have checked her purse for it because that's where it most likely would be if she'd had it with her. But if he did check her purse, he would have seen all that "equipment" from Stella in there. But Gloria still has it when she comes to consciousness. What kidnapper would leave weapons in her reach?

Audio problem: The scene in Dudley Moore's apartment was longer than the song, "Stayin' Alive" that is playing on his stereo so the song is substantially longer by looping and replaying portions of the song.

Plot hole: When Gloria picks up Scotty on the road towards the beginning of the movie, they are being followed by the black car. But if Scotty had been being followed, the car would have easily caught up to him when his car broke down.

Continuity: When Scarface is holding Gloria as he asks "Where is it?", watch her arms - from the side, we can see her left arm is arched outward; however, from the view behind Scarface and facing Gloria, her hands are pressed together in front of herself, in a defensive position.

Continuity: In the scene where Chevy Chase is driving the stolen cab out of control, there are Japanese tourists in the back of the cab. When Chevy drives the cab over the construction sand you'll see that Chevy is replaced by a stunt man and the Japanese couple have completely vanished.

Continuity: When Chevy and Goldie are racing to save the Pope in the stolen taxi, after he jumps the dirt mound at the construction site the hood opens upon impact when the car lands - but in the next shot the hood is closed again.
