The Hidden (1987) - 4 major mistakes

Continuity: When Beck and Gallagher are chasing the stripper (Claudia Christian) Gallagher shoots out the wheel of the stripper's car, which then proceeds to crash into a mannequin warehouse. As Beck and Gallagher approach the suspect's car there is the head and hair of a mannequin showing out the broken back window. Obviously from when Claudia Christian crashed into the warehouse. However the front car windscreen is unbroken as Beck passes it. So how did the mannequin enter the car?

Continuity: 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: When DeVries runs through a sheet of glass killing two workmen, a large bloodstain appears on the windscreen. When he speeds up before the police roadblock however, it's almost disappeared. When the cops start shooting, it's back.

Continuity: Shortly before DeVries encounters the police roadblock, he emerges over a hill, closely followed by two police cars. When the shot cuts to the roadblock then back to DeVries, no police cars are visible out his rear window.
