Continuity mistake: At the beginning of the car chase a silver Hillman Hunter is parked on the left hand side of the road when the squad car is chasing after Sleeman. It wasn't there a few seconds earlier when the camera was following Sleeman's car.

Continuity mistake: After Fischer drives away after hitting the mini he passes Sleman's parked white Renault but when the camera switches to inside the car Fischer passes Sleman's parked car again.
Visible crew/equipment: When Fischer reverses into the Mini you can see the camera lights reflected into the side of the car Fischer is driving.
