Continuity mistake: Kiefer Sutherland plays washed up Detective Mickey Hayden chasing serial killer "Jabberwocky". In the very last scene he's walking through the park, stops at the sound of a distant gun-shot, and flips his cigarette butt away. The next shot, coming up to his parked car - he has a brand new lit cigarette and he flicks that one away too... (01:33:00)
Continuity mistake: In one scene we see a police officer investigating his colleague's disappearance. In the long shot we see him walking towards the other police car and it can be seen that the number plate is a fake. A fake paper number plate has been placed over the original number plate. When the wind blows you can see the side of the paper blowing in the wind. (01:16:05)
Continuity mistake: In the first movie, it took quite some time (days if not weeks) for Tomie to regenerate back her full body. In this film, it seems to happen in mere hours after her head is placed into the tank for observation.
Continuity mistake: When the Young Gangster and Freddie Mays go to see Lennie Taylor, after the guys have beat the man up with the golf clubs, Freddie and Young Gangster get out of the car and start to walk up the street.
