Factual error: Colonel von Lindeiner was not executed. He testified to the investigation into the Gestapo murders and died in 1963 at the age of 82.
Continuity mistake: When the killer is using the R/C car bomb to follow Harry and his partner; as the R/C car approaches Harry's stopped car, it starts to swerve to the left, as if to go around. However, in the next shot, the R/C car is perfectly straight again, and lined up to go under Harry's car.
Continuity mistake: When Charlie (in Marshall's body) goes to the final executive meeting, he dons a pair of glasses with an ear receiver attached by wires to one of the bows. When he removes the eyeglasses prior to leaving the meeting, the earpiece remains in his ear.
Suggested correction: It was established when the salesman was talking about the device that the part attached to the glasses was the antenna and it came with a separate earpiece.
Revealing mistake: The dead cop can be clearly seen sitting up even though he's dead as the lady cop tosses the chair through a window. The next shot he's back to being dead again. (01:16:00 - 01:17:15)
Continuity mistake: During the whole scene where Tess says good-bye to her colleagues, up to the moment when she gets out of the elevator, drops her stuff and picks it up her hair is messy and straggly. When she gets up and sees Katherine it's perfectly done up. (01:34:20)
Audio problem: When Melissa and Stacey go to the singles party at the health spa, they approach Jamie at the bar. Jamie states that the drinks are all made up of 98% mineral water just like your body. Melissa then says that if the drinks were anything like her body, they'd be made up of 98% ice cream. However that's obviously not what her mouth is saying. She appears to say Twinkies.
Continuity mistake: In the scene were Jake is in the bed already after telling Christy he was really tired and didn't want to be bothered he rolls over. She comes out of the bathroom & of course fanning the room from all of his cologne. Christy lays down in bed flat with no pillow behind her head. In the next scene showing Jake's face & Christy behind him in bed she now has a pillow under her and is much higher up in bed.
Continuity mistake: When Igor grabs Tara and pulls her inside the truck, Tara drops the tomato twice between the shots. (00:54:40)
Continuity mistake: When Randy Quaid is trying to make the shot on the giant windmill, he swings and hits the ball. You can see the ball flies almost vertical and way to the right of the windmill. However the next shot shows it landing right on target.
Visible crew/equipment: When Mel Gibson is getting his red boat ready to put in the water, his friend comes out of his house to talk to him. You can see the camera crew reflected in his friend's sunglasses.

Plot hole: When Gary Busey infiltrates the Mexican terrorists' compounds, he first throws a stick to distract some guards and kills them. A few minutes later a terrorist officer reports to his boss that Gary Busey has killed three of his best men. Are we to believe that the three best terrorists were tricked by a stick thrown into some bushes, and then easily killed by an unarmed assailant (they had submachine guns)?
Continuity mistake: Billy has a magic baseball uniform - at the end of the movie, he steals home again, sliding face first into the plate on his stomach. Yet when he's walking off the field with Robin and Appleby, there are no dirt marks on his uniform.
Visible crew/equipment: In the scene where Randall is chasing the big blue, he trips and if you look closely in the background, a camera is perfectly visible..

Continuity mistake: The actress loads her 35mm Praktica camera with Kodak film. That's not really strange, but the film is situated in 1968 around the invasion of the Russians in Prague. The film cassette is clearly visible as having DX coding on one side for setting the film speed automatically. This feature had yet to be invented in 1968, because it was released in the early 80's.
