Friday the 13th Part VII: The New Blood (1988) - 45 mistakes

Revealing: 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.

Continuity: When Dan is in the woods the amount of wood he is carrying decreases.

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.

Other: 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.

Revealing: When you see Jane pinned dead to the tree you can see her pulse.

Continuity: 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.

Continuity: 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.

Continuity: When Tina uses her psychic power to hang Jason, the size of the hole he falls through changes between shots.

Continuity: 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 the movie.

Continuity: When Tina is driving, she swerves to avoid Jason. The trees that she almost hits change between shots.

Continuity: When Tina battles with Jason, the height of the basement roof drastically differs.

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.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Revealing: 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.

Revealing: 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.

Continuity: 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.)

Continuity: 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.
