Continuity mistake: The way Marcy is holding the towel when she notices the rashes on her back changes in the closeup. (01:03:10)
Continuity mistake: When Marcy and Paul are talking about their hopeless situation "being like being on a plane that's going down" you can see a small wall hanging to the left of the glass panel door in the background. Also, the shadows from the hanging and door frame cast left, away from the door. Later, when they have sex in the same bedroom, the wall hanging is on the right side of the door and now its shadow casts towards the door. It's definitely not the opposite wall of the room, as this is shown earlier and has a wood-plank door, a much larger painting mounted on it and unlike the wall shown in these scenes, it isn't wallpapered. (01:01:35 - 01:02:30)
Deliberate mistake: The sex scene between Paul and Marcy is broken up with a shot of Karen dying alone in the toolshed. The shot is well-lit, but we saw Marcy closing the door when she put Karen back in the shed, leaving the shed virtually pitch dark. So where is the light coming from? (01:02:35)
Continuity mistake: When Paul and Marcy start having sex, Marcy's hair is running down her back. Paul asks Marcy about whether they should use a condom. Cut to a close-up of her face for her reply and her hair is suddenly hanging over the far side of her face. Cut back to the original angle and her hair is running down her back again. (01:02:30)
Continuity mistake: When Marcy first runs out of the cabin, just before she dies, her chest is clean. But in the few seconds it takes her to run to the nearby toolshed, somehow her chest gets covered in splotches of blood. (01:10:45)
Revealing mistake: When Marcy and Jeff are having sex, at one point Marcy rolls over on top of Jeff. When she does this, there's a couple of instances where you can see a red cord from the bikini bottom she's wearing to preserve her modesty dangling down in the background. (00:14:05)
Revealing mistake: As Marcy is running away from the mad dog, there are a few instances when we can see the sleeve of a white top inside her bathrobe. She was supposed to have just run out of the shower in a panic, so throwing on a top and then a bathrobe doesn't seem like something she really would've done. (01:10:55)
Continuity mistake: When Paul squeezes Marcy's back during sex, his fingers are pointed more inwards towards her spine then upwards towards her shoulders. The hand-shaped rashes Marcy notices in the bathroom immediately afterwards reflect this position, also. But as the rashes deteriorate, the finger marks shift into positions that are completely different to the way Paul was holding her. (01:02:35 - 01:10:30)
Revealing mistake: There's no chimney on the roof, but the fireplace works.
Visible crew/equipment: Boom mic visible when Marcy is looking at her back in the mirror.
Continuity mistake: When the kids are in the shop near the beginning of the film, at the shopkeepers desk is a cardboard box, and next to it are some jars and tins. Between a couple of shots the jars/tins rotate and move position on the desk, and also two or three jars/tins appear then disappear. (00:07:30)
Revealing mistake: In the cave scene, when Paul finds Grim's body, during the "worm in the ear" shot, Grim's neck is moving quite visibly with his pulse. (01:11:20)
Continuity mistake: When the blonde goes to kiss her boyfriend as they are floating on a platform in the lake, she rolls herself off the platform and completely submerges herself underwater. When she comes up for air, it cuts back to her boyfriend looking at her, then back to the blonde who is head above water and her hair is completely dry. (00:14:20)
Continuity mistake: When Marcy, Bert, Jeff and Paul are in the cabin talking about the fact that maybe they should prepare their own meals, during the conversation before the scrap between Jeff and Bert, watch Marcy who's sitting on the couch. Between shots she goes from having her hands up in the air, to folded or down in her lap. (00:52:00)
Revealing mistake: When the police are throwing the bodies on the fire near the end of the film, the body that gets thrown on top is obviously a doll. The body on the bottom looks like it possibly could be, but the one on top is definitely one. (01:25:50)
Visible crew/equipment: At the start of the movie when the teens are heading off to the woods in the Jeep, in one of the backseat shots, you can clearly see a cameraman in the rearview mirror. (00:04:00)
Visible crew/equipment: When Paul pokes the dead body with a stick, you can see a diver's arm turning the corpse over.
Other mistake: The Blazer was only hit twice by the baseball bat, once on the right front fender, and once on the grille, but it sustained a massive amount of damage. Also, when the infected guy was inside, throwing up blood, you could see that the windshield was cracked in several spots, but it was never hit.
Continuity mistake: When Marcy leaves Karen's side to confront Jeff, in the first shot Karen's blanket is tucked under her legs. But in the next shot, her blanket is lying loose upon her mattress. Also, leaves that are bunched up at the side of the mattress disappear between shots. (01:00:50)
Continuity mistake: Right at the end, when Paul checks on Karen (obvious dummy), she is lying on her right side while the dog is attacking her. After Paul gets chased out by the dog and kills it, he returns, and Karen is now on her left side. She didn't have the strength to move when the dog was biting her, so how could she turn over?
Answer: It was never revealed.
