Revealing mistake: When Jack and Marty are shot at in the hotel room and the second bullet hits the window the glass pieces are flying from a different spot from where the hole appears. (00:33:25)
Continuity mistake: When the Sheriff inspects the damaged window the second bullet hole is gone. (00:33:50)
Revealing mistake: When Jack and Marty drive the skinny lady to her inbred folks Jack follows one of them into his house. He has a terrarium where a snake is just swallowing a screaming but otherwise lifeless rat. (00:50:15)
Suggested correction: The rat's last dying gasp? Morticians will also tell you that if you compress a corpse's chest, the deceased will make moaning noises as air from the lungs is forced out and past the vocal chords. Why couldn't the same process happen with a rat?
Revealing mistake: Jack pierces the snake owner's hand with his pen with the hidden blade. In close up you see that the hand is a prop: it has a different colour, and there is already a mark where the blade is about to go through. (00:51:20)
Continuity mistake: After the car crashes through the gate and Jack and Marty jump out it finally goes down a cliff. The dent from the crash is gone when the car is flying though the air. (00:53:55)
Continuity mistake: When the car falls off the cliff you see that the passenger airbag is blown up. In the next shot from the side there is no airbag. (00:53:55)
Continuity mistake: When Marty talks to Cindy in her bed her bangs differ in close up and wide shots. (01:03:15)
Plot hole: When Marty lies on the conveyer belt on the way to the stone crusher he tries to wiggle off the belt. The little he seems to be able to move is not justified by the way his hands and feet are tied up. (01:08:30)
Revealing mistake: When Jack's car falls down into the quarry there is not only the notorious exploding motor but also another explosion in the back for which there is no reason. (01:11:15)
Continuity mistake: When Cindy's jeep crashes into the mine building it is shown in three shots. In the first two the jeep bursts though the right side of the gate, in the last one through the left. (01:18:30)
Continuity mistake: When Jack is trapped in the mine under a pile of wood the arrangement of beams changes from shot to shot. (01:25:00)
Continuity mistake: After Lionel Pond, the mine owner, dies from a heart attack he sits in his wheelchair with his head sunk deeply between the shoulder pads of his jacket. In the next shot he is sitting straight. (01:28:00)
Revealing mistake: When Jack and Marty go back to LA they drive by two stuffed but nevertheless mooing elks. (01:29:05)
