Continuity mistake: When Beck meets Webly on Christmas Day, Webly takes his glasses off and throws them on the desk, but in the next shot (from behind) he is still wearing them. (00:16:50)
Continuity mistake: When the patrolman is killed at the start of the film, 8 shots are fired. The first is fired with the pistol inches from the center of his chest while he is standing. The remaining seven are fired while he is lying on the ground (gun is pointed down at the ground where the unseen policeman lies). The shooter then runs off. Yet when the scene is investigated, there are five bullet holes in the rear door of the police car, all below waist level. (00:07:40 - 00:08:40)
Continuity mistake: When Beck tackles the fleeing suspect after the foot chase, a wide shot shows Beck kneeling over the suspect with his sport jacket's bottom-half folded upward, exposing the lower half of the back of his shirt. In the next shot, close-up, the jacket hangs normally even though the two shots are in consecutive time. (00:23:20)
Factual error: Three different characters (including two police officers) describe the car driven by the bad guys as being a maroon Ford wagon. Yet in the two scenes showing the car, it's a Pontiac.
