Continuity mistake: Near the beginning of film, Peter Boyle's character opens a newspaper, and on the front page is a story about a death row inmate who is scheduled to die "tonight." However, he does not die "tonight," but rather the following night. On the evening of the day on which the erroneous newspaper headline appears, the prison guards gather at a local bar. The next day, the prisoner is taken to a special cell to await his execution, which occurs TWO nights after the newspaper headline said he was to be executed. (00:08:15)

Continuity mistake: When Peter Boyle is talking to Halle Berry, he asks her for a cigarette, and he smokes it. But there's one shot where you see Boyle's profile in the foreground, and Berry in the background, and he has no cigarette in his mouth. Also, we hear him say something there, but his mouth never moves. (01:25:40)
Continuity mistake: Buck can hardly move around due to his lung condition. After he insults Leticia and she runs out of the house and drives off he makes it out to porch way too fast. Then, in the next shot, he is seen sitting with his oxygen kit on, which he wasn't wearing before. (01:26:30)
