Visible crew/equipment: When Samanth is pretending to hid underwater until Sarah agrees to go swimmming, when Sarah is searching for Samantha, is shows a shot of Samantha coming from underneath the docks. When she does, you can see it is a dummy coming from underneath the docks.

Continuity: When Jimbo gets his hand impaled on the counter with a corkscrew by Jason, the counter is clear, but a few scenes later as Jason leaves the kitchen, there's a pot holder laying on the counter.

Continuity: When Trish's car stops, the licence plate goes from dirty to clean.

Revealing: Trish tells Tommy to go get a hammer and some nails. When Trish then shouts "Tommy, hurry" you can see the shelf to her right get bumped by somebody in the crew, who was obviously standing nearby.

Continuity: When Tommy is looking under the hood of the broken down car, it shows someone approaching and you see that they are wearing grey trousers. The person ends up being Rob, but Rob wears black trousers.

Continuity: After electrocuting Jason with the TV, he falls backwards, and the door is left open. When Trish and Tommy walk over, the door is shut.

Revealing: Near the end when Jason throws the hammer at the girl, it sticks to the damaged part of the wall after it hits. But it's just against the wood with the flat top, there's nothing to hold the hammer there and it's only hit the wood on the other side of the wall. They probably used a magnet to attract and keep it there for safety reasons.
