Continuity mistake: When Rick is about to go for a drive in his car, and Chris is begging to come, we see Rick is holding just keys and that Chris's hands are empty. It cuts to the POV of Jason watching them from the stable, and Rick hasn't moved or picked anything up. It then cuts back to a closer view of them again, and now Rick has a golden coloured coat in his hand. (00:33:50)
Continuity mistake: After Edna yells through the window at Harold for knocking down the clothesline pole, she slams the window shut and the end of the curtain gets trapped under the window. Then the scene cuts to show Edna from the inside, and look at the curtains from this shot. They are now hanging straight down, just like it should be and aren't trapped. (00:08:10)
Continuity mistake: When they arrive at the lake and get out of the van, the long shot from the passengers' side shows Chris getting out and slamming her door, but then the next shot from the driver's side shows her getting out and slamming the door again. (00:21:55)
Continuity mistake: When Jason swings the machete to kill Andy, he swings vertically, which would have cut him between the legs down to his head, as he was walking on his hands. Later when Andy is shown, he is cut horizontally at the waist. (01:00:15)
Continuity mistake: When the cops arrive at the store, they approach and the white cop comes in contact with someone to move them away. The camera then shows the van driving, with the passengers all looking down at the store. The next scene then shows the 2 cops approaching the store again.
Continuity mistake: When Shelly and Vera get into the car after their run-in with the biker gang, you can see the area around where the windshield wipers are attached to the bonnet is all perfectly painted.

Continuity mistake: When the "stoned" couple makes popcorn, it is shown being poured from a pot on the stove into a bowl, cooked properly. A short time later when Chris and her boyfriend are searching the house they come upon the pot of popcorn on the stove burning, and they empty it again.
