Continuity mistake: While at the pool hall, Mary indicates that the sign in the window describes Larry perfectly. A close-up shows it reads 'Out To Lunch', but the next wide shot shows it reads 'We're Closed'. (01:01:45)
Continuity mistake: The people inside the elevator disappear in the wide angle. (01:57:21 - 01:57:51)
Continuity mistake: The small plane's pilot identifies the aircraft as 232Z. But in the exterior shots, the aircraft's identification is N9750Y. (00:35:00)
Other mistake: In the original version of the film there's a mistake in the opening credits where Colin Blakely's name is misspelled as Colin Blankey.
Revealing mistake: During the quake, a mother is seen having a plate glass window fall on her face while her daughter screams. Before the mother turns around to show us the gore, look close and you can see a shard of glass already "placed" in her face before the fake glass falls her. Additionally, while not a "mistake", it's clearly a "stuntman" portraying the mother. The face and yelping give it away.
Suggested correction: It was a stunt woman. She was no beauty queen. Her name was Stevie Myers.
Other mistake: When Hyman Roth's assassin runs at the airport, he is turning around with one (of two) bullet holes already in his jacket before the sound of any gunfire. (03:10:50)
Continuity mistake: When the guys use the key to steal the car, its back license plate number is 4N-4290, but when Chico pulls into the drive-in, the front plate number is SV-5875. Then when Chico reverses the car, the front license plate number is 4N-4290. (00:42:40)
Visible crew/equipment: After Lightfoot steals the Trans Am, when he first encounters Thunderbolt on the run, he swerves into the field, and in a shot from inside the car, a piece of filming equipment on the hood of the car is visible through the windshield. Then Lightfoot hits Dunlop with the car. (00:07:50)
Revealing mistake: Whilst being followed by Celine, Julie walks up a small flight of steps. When this happens, a blue car can be seen turning around a corner and driving past the camera. Just as Julie walks into frame, the driver of the blue car can be seen looking at the camera just as he drives past it. (00:05:58)
Revealing mistake: When Butt falls behind the suitcases, a mattress to soften the fall is visible.
