Continuity: Early Grayce seems to be driving two different Pontiac Grand Prix in the opening scenes; the headlights differ.
Continuity: When Kessler and Carrie are having sex at the motel, Carries right bra strap is alternately on/off between shots.
Continuity: When Early is digging the hole at night and talking to Adele, you can see the top of his pants. When he climbs out of the hole, he is obviously naked.
Continuity: The amount of vodka in Carrie's glass changes inconsistently between shots while she's sitting on the couch, watching her slides, trying to convince Brian to go to California.
Factual errors: When Brian and Carrie visit the murder scene, Carrie's Nikon clearly has a motor drive, and we hear the sound of it advancing the film, but we also see her manually advancing the film.
Continuity: Towards the end of the movie, Brad and David are eating Chinese food. In one shot, you see David open his container. In the next shot you see him open it again.
