Revealing mistake: When Tina kills her father and the dock collapses, one of the logs hits the camera underwater. (00:06:40)
Continuity mistake: Melissa's position instantly changes between shots as Tina is going to the boot of her car to when it cuts to a closeup of Melissa speaking. (00:08:05)
Continuity mistake: When Dr. Crews and Mrs. Shepard first arrive at the cabin, the bags/cases they carry change between shots. (00:08:15)
Continuity mistake: Tina's pink t-shirt that Mike notices by his feet, which fell out of her suitcase, is not actually there in the shot beforehand and simply appears. (00:09:10)
Continuity mistake: When Tina has run down to the decking (in the scene when she releases Jason from the lake) the prominence and position of tears on her cheeks keeps changing. (00:14:00)
Continuity mistake: The bullet hole that Sheriff Garris shot above Jason's eye in Friday the 13th Part VI: Jason Lives is missing from the mask in this movie. (00:14:30)
Continuity mistake: When Tina opens the door for Nick, the fridge door has magnets, an organizer and a cloth on it. Later when Tina's mum closes the fridge door everything is now off the door except for a magnet. (00:17:00 - 00:31:15)
Continuity mistake: When Jane is waiting for Michael in the forest in some shots she is standing right beside a tree, in others no tree is visible (although it would be in shot if it were there.) (00:18:40)
Continuity mistake: Just before Jane is killed in the woods, you see her standing with her arms crossed from the back. When it cuts in front of her she is crossing her arms again. (00:18:50)
Revealing mistake: When Jason lunges at Jane in the woods before killing her, in this closeup you can clearly see Kane Hodder's normal human right eye. (00:18:55)
Revealing mistake: When you see Jane pinned dead to the tree you can see her pulse. (00:19:15)
Revealing mistake: When Jason pulls the tent spike out of Jane's neck, her eyelids flutter. (00:19:20)
Continuity mistake: When Eddie is reading stuff from his pile of paper you see the pile is disordered. When it cuts to the pile, it is fine. (00:20:20)
Revealing mistake: When Dan is gathering wood for the campfire, in the shot when he splits a log with his machete you can clearly see that it was already broken. (00:25:20)
Suggested correction: It also shows him swinging the machete once before breaking in half. A machete wouldn't be strong enough to cut the log in half with just 1 swing. The log was obviously being struck before it broke.
Continuity mistake: When Dan is in the woods the amount of wood he is carrying decreases. (00:25:35)
Continuity mistake: When Jason swings the girl in sleeping bag against the tree, he grabs the head end, yet the head end is the one that hits the tree. [This is fixed and not a mistake in the uncut editions (theatrical and new release dvd) because the uncut scene has Jason taking six swings with the sleeping bag against the tree, including the head end.] (00:26:50)
Continuity mistake: When Jason shoves his fist through Dan in the woods his fist is bloody, but when he kills Dan's girlfriend, the blood is gone. (00:27:00)
Continuity mistake: In the scene Robin tells Maddy she's going to get David, a cup of coke on the counter vanishes for a shot, the green napkins move around, and the blue flowery pattern on the bowl disappears and reappears. (00:30:50)
Continuity mistake: When Robin tells Maddy that she's gonna stick with the deal and "have a good time" she opens her arms up twice between shots. (00:33:10)
Continuity mistake: Russell's dead body, lying on the shore, is in the wrong position. He crawled away from where he was sitting and was hacked in the face and fell backwards. Yet in the shot of him dead his head is resting next to where he was sitting originally. (00:35:40)
