Continuity mistake: When Jim and Grace are driving away from the police in the stolen sheriff car, they are shot at and the back tailgate and left wing mirror are broken by gunshots. But in following shots you can see both parts of the car completely intact again, the broken, fixed, etc. (00:48:40)
Continuity mistake: In the scene when the police are chasing after Jim and Grace, Ryder suddenly pulls up and shoots one of the policemen. Then two of the cruiser cars collide and skid down the road. During this scene the metal barriers on the sides of the road keep disappearing then reappearing. (00:49:30)
Continuity mistake: Near the end of the movie, when Jim and Grace break into the motel room to clean up and rest, they enter the window of unit 12, with the door to the right of unit 11. After Jim has left the room, and Grace is woken up, she leaves the room through the door, which we now see is unit 11, the door on the left.
Continuity mistake: Right after the initial fight scene in the car with John Ryder, after he is kicked out of the car, and Grace gets back into the front seat, she reaches behind her and locks the passenger door. In the next shot, when she is looking for her cell phone, the door lock is not depressed. Some older Cutlass 442's had lock barrels that were higher than normal, or were screwed on less than others, but this appears to be a fully extended lock barrel.
Continuity mistake: After Ryder has destroyed all the police cruisers with his Trans Am, there is a shot from the police helicopter looking down at him driving. Ryder is wearing black gloves, but in the immediate next shot, they've now gone.
