Revealing mistake: When you see Jane pinned dead to the tree you can see her pulse. (00:19:15)
Revealing mistake: When facing Jason after he throws Melissa with an axe in her head, you can see that the eye holes on the mask he wears are covered with black cloths. (01:13:50)
Revealing mistake: When the fireman picks up pieces of the hockey mask, the pieces are too thin and fragile to be a hockey mask. (01:20:40)
Revealing mistake: When Tina kills her father and the dock collapses, one of the logs hits the camera underwater. (00:06:40)
Revealing mistake: Obvious stunt double for Tina as she drops the porch roof on Jason and when Jason grabs her and throws her onto the dock. Her hair becomes a smooth blonde wig.
Revealing mistake: When Jason pulls the tent spike out of Jane's neck, her eyelids flutter. (00:19:20)
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.
Revealing mistake: When we see the shot of David's head, you can definitely tell it's a prop head.
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)
