Continuity: There is a scene during the cops' frantic search for the first missing girl where a red-headed lady cop is sitting at a desk with a computer screen. On the screen, however, is the picture of the SECOND girl, not the first one. The picture of the second girl hasn't even been sent to them yet.

Continuity: In the scene where James Spader and another cop are at the Vietnamese restaurant, there is a front shot of the cop putting food in his mouth with some chopsticks, then the camera cuts to a side angle shot and the chopsticks are nowhere near his mouth.

Continuity: In the scene where James Spader meets Keanu Reeves in the graveyard, we first see a Ford Taurus taxi driving through the gates, but when Spader gets out, the taxi is now a Chevy Caprice.

Continuity: During the escape from the building he killed the second girl in, Keanu Reeves smashes a car window with a toilet bowl. In the next scenes (while being chased by the police) the car has no smashed window anymore.

Continuity: When Keanu is burning and jumps out of the window, he dies when he land in the water. Then when James looks at him, he is floating. Dead bodies do not float until after 2-3 days when the body swell.
