Continuity mistake: In the final scene of the movie, the step van which drives off the pier is not the same one they were chasing. The one they were chasing was a Chevy, while the one that wound up in the water was an International. (01:10:00 - 01:18:00)
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: When Jack Forrest is leaving his wife behind to go on night duty, there is sunlight coming through the window.
Plot hole: It is explained that due to the severe beating/stabbing Cordell received in prison, he has no "higher brain function." How does this make him impervious to gunshots?
