Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.
Continuity mistake: In the scene where Eric kidnaps T-Bird and forces him to drive the hot-rod to the dock, Eric holds a large silver revolver up to T-Bird's head, then removes a black automatic from T-Bird's hand and drops it into the front floorboard. A few moments into the chase we see Eric holding the black automatic to the side of T-Bird's head, and the silver revolver is gone.
Continuity mistake: When Lee takes T-Bird in his car and the chase with the Police begins, the camera flashes to look at the chase through the eyes of the crow, the Police cars emergency lights are strobes, but when the camera reverts back to the chase scene they are the old style rotating flashers.
Continuity mistake: Watch T Bird's facial scars, they change from small to big throughout the police chase.
Continuity mistake: When Funboy gets shot in the leg it hits his right, he is then shown clutching his bloody left leg and then his right when he is dragged into the bathroom. It goes back and forth like this. (00:38:20)
Continuity mistake: When Eric is about to leave Gideon, he points the shotgun at him, then holds it vertically. Just after he says "your job is to tell the rest of them..." we see a shot of Gideon, and the barrel of the shotgun is visible in the top left corner, pointing at him again. Back to Eric, and the shotgun's still vertical. (00:30:00)
Continuity mistake: After Eric spreads petrol (or something ignitable), he leaves Gideon's Pawn Shop with the shotgun full of rings. When standing outside, he shoots the shotgun into the building. First of all, I doubt that even petrol could make such a big explosion. Secondly, if you watch closely, the top of the building seems to blow up before the bottom. (00:31:05)
Continuity mistake: When Sarah is skateboarding, and the guy in the car yells at her to get out of the road, she pushes with her right foot and has her left foot in front (a "Regular" stance), but in the next shot she is riding "goofy" stance (right foot front), with no time to change stances.
