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: Robin's position changes when she is thrown out of the window.
Continuity mistake: The tent that Judy and her boyfriend are camping in changes size between shots.
Continuity mistake: Jason has on an entirely different outfit in this movie than in part 6. Since he was chained in the lake there would be no reason for his clothes to be different.
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)
Continuity mistake: In the prologue with the narration, you see the scene from six where lightning struck the pole to revive Jason. You also see Jason's tombstone shattering during the lightning strike. In six, you never saw the tombstone breaking.
Continuity mistake: As Tina is speeding away in the car after finding out that Crews wants her committed, she passes by a car that is supposedly the one belonging to Michael and his girlfriend. It is facing in the same direction as she is. If they were coming up to the place for the party, wouldn't their car be facing in the opposite direction, and on the opposite side of the road, which is where we saw it stop earlier in the film?
Continuity mistake: When Amanda Shepard's watching the video of Dr. Crews forcing Tina to move the matchbook, on the left side of the screen, there are two plaques on the wall two inches apart from each other, but in the next shot as Dr. Crews enters the room, the plaques are now four inches apart.
Continuity mistake: The scene where the AA couple is having sex in the van, the guy suddenly has shoes on when he exits looking for Jason. You see him supposedly putting on his pants under the covers, but no shoes.
Suggested correction: We don't see everything he does under the covers. Plus it cuts to the outside and showing him exit the van, but we are not given a time frame of how long he was in the van before he exit's it.
Continuity mistake: When Jane is killed, blood comes out of her mouth. Yet there is no blood when Michael sees her pinned to the tree.
Continuity mistake: The ax cut is gone when the fireman picks up Jason's mask.
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: 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)
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 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: 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.
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 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)
Continuity mistake: The video monitor and VCR on Dr. Crews' desk disappear as Tina looks at the picture of her father. Additionally, there is a model train on the desk in some scenes, but not in others.
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)
