Continuity mistake: When the two cops pull the stripper over, their car stops in the middle of the road. When Beck and Gallagher pass them later, however, their car is closer to the pavement. Their car moves yet again when Beck looks back at them out of his window. Also notice that three headlights are now on, including one that the stripper blew out.
Continuity mistake: When DeVries gets out of the Ferrari covered in blood, Willis is seen pointing a pistol at him. When the police blow up the car, he is using a shotgun. In fact, when they blow up the car, most of the images used are the same shots of them firing at the car before it hit the roadblock, only they're flipped. Willis also appears to switch from a right handed shooting stance with the pistol to a left handed shooting stance with the shotgun.
Continuity mistake: When DeVries is being chased by the cops, he passes some roadworks. At first there is only one wooden barrier in his way, with a workman about to position another one. The next shot shows two in place. DeVries appears to knock these over, but in the following shot he only hits one, with the other one transported to his left, ready for the cops to knock over.
Continuity mistake: When DeVries' Ferrari crashes into the fence, the license plate is lying crooked, touching the bumper. When the cops blow it up, it's not touching the bumper. Also notice that the petrol tank and exhausts have been removed, revealing that the car blows up by explosives rather than police gunfire.
Continuity mistake: When the Ferrari boss calls Eddie to help deal with Miller, two guys wearing suits are standing in the sunshine next to a grey car. When Miller refuses to take no for an answer after being thrown out, you can see that the guys are gone and the car is now covered by a shadow. The red Ferrari also now has a longer shadow.
