Continuity mistake: In the shot where Sandra notices Russell's dead body lying on the shore, Sandra's trainers are lying right next to her shirt and shorts. In every other shot her trainers are nowhere to be seen on the shore. (00:35:50)
Audio problem: When Jason pulls Russell's girlfriend underwater, you can hear her screaming as if she's still above the water. (00:37:50)
Continuity mistake: When Crews is opening the drawer to take out the iron pole you can see the pole changes position in the drawer between shots. (00:38:30)
Continuity mistake: When Tina's mother takes out the video cassette she doesn't close the video cover. When it cuts to Crews entering, the cover is closed. (00:41:05)
Visible crew/equipment: As Tina swerves off of the road after seeing her mum get killed by Jason in the middle of the road, if you look in the back of the car, you can see a camera set up, filming the shots in the back seat. (00:43:15)
Continuity mistake: When Tina is driving, she swerves to avoid Jason. The trees that she almost hits change between shots. (00:43:15)
Continuity mistake: When the girl is looking for her earring she kneels down beside a huge tree. Then suddenly the tree is gone. (00:45:25)
Continuity mistake: In the scene where Maddy hides from Jason, she is barefoot. In one shot she sees him, and bends down and grabs her shoes. In the next shot she picks them up once again. (00:49:00)
Continuity mistake: When David says "The neanderthal man...," he puts his right hand on the girl's chest. When it cuts back his arm is no longer there. (00:53:35)
Visible crew/equipment: When the girl is knocking on the door while saying "Maddy?" you can see several shadows from persons moving alongside the wall beside her, even though she is supposed to be alone there. (00:59:15)
Visible crew/equipment: When the girl is looking for David in a dark room you can see the film crew member holding the microphone reflected in the window while he is moving it. (01:00:00)
Continuity mistake: When Jason throws the girl out the window he throws her with her back first. When it cuts from the outside she is coming out the window face first. (01:02:00)
Continuity mistake: When the girl is thrown out the window you see her falling with her right shoulder first while crouching. In the next shot she falls directly onto her stomach. (01:02:05)
Visible crew/equipment: When Jason is walking down in the forest you can see three spotlights on the upper right. (01:02:55)
Visible crew/equipment: When Jason pushes Dr. Crews down the hill, as he's falling, you can see some kind of equipment attached to the back of his pants. (01:10:45)
Continuity mistake: As Jason steps out of the puddle, his clothing is dripping wet. Then in the next shot as he walks after Tina, his clothes can be seen, dry. (01:10:50)
Continuity mistake: Outside the house when the last pillar on the porch breaks we can see Jason looking up and then to the side. When it cuts he looks up and to the side again. (01:12:30)
Suggested correction: Because he's reacting to the noise and each part of the roof falling off each time.
Other mistake: When Melissa opens the front door and Jason is standing there, he raises his right hand, holding an axe, and plunges it straight down. But when Melissa has the axe in her head it is on the opposite side and at a different angle than it should have been. (01:13:45)
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)
