Visible crew/equipment: During the scene where Chopper shoots Sammy the Turk in the eye with the shotgun in the car park behind Bojangles, the pregnant woman runs back to the car after witnessing the shooting, you can see the boom mike in the bottom right of the car's windscreen.
Continuity mistake: 1st shot: Chopper's girlfriend leaves the car; the headlights are on. 2nd shot: Chopper leaves the car to go up to her stoop to talk to her (through a closed door) and after she refuses him, he runs back to his car (old-school vehicle, far before the advent of headlights that turned themselves off) and 3rd shot: the headlights are OFF.
Continuity mistake: When Chopper and co. are in jail planning, one of the two men stabs him continually. It goes to a shot from behind Chopper and you can see that the knife has no blood on it.
