Friday the 13th Part VIII: Jason Takes Manhattan (1989) - 95 mistakes

Continuity: By the radio on Jim's boat is a bottle with a boat in it and the cork in the bottle is pointing to the left side. When Suzi gets up to check on the noise, the bottle is visible and the cork is now pointing to the right side.

Revealing: When Jason kills the boat captain he comes up way short of making contact with the captain's throat. He's probably a good 2 inches away from it. It definetly doesn't help that this scene is in slow motion either...

Revealing: As Sean dives into the water to save Rennie, in all the overhead shots Rennie has dry, curly hair, but in closeups her hair is soaked down straight. In the overhead shots it's obviously a stunt double.

Revealing: Throughout the movie, the black cloth covering Jason's eyes under the hockey mask is really noticeable, especially when he grabs onto the rope to climb aboard the Lazarus.

Continuity: When Jason grabs the man in the diner he is several paces to the right of the mirror, but when he throws the man into the mirror Jason can clearly be seen in the reflection standing right across from it.

Revealing: When Jason strangles Eva, you can see where the rotten flesh makeup ends on his arm, and that the rest is just a fabric sleeve.

Revealing: In the scene in which Jason kills the captain of the boat, it seems as though Jason uses the wrong side of the blade to cut the captain's throat.

Continuity: There is a large blue cooler by the stairs in the boat, under two postcards. But in the shot where Jason clips the harpoon, before shooting it, we can see the cooler has vanished.

Continuity: In the scene where Tamara gets out of the shower, her silk gown which hangs on the handrail changes position between shots.

Continuity: When Wayne is taping J.J., between shots his left hand moves from down by his side, to on the focus of his camera.

Visible crew/equipment: When the boxing scene starts, as the camera pans past the punchbag, the shadow of the camera is clearly cast on it. Then as the camera continues to pan past the punchbag, you can see the sides of two crewmembers come into view (who are following the path of the camera.) They are both wearing a jumper and jeans.

Visible crew/equipment: When Rennie is searching for Toby, the camera then pans to the games room, and reflected in the four pictures hanging up on the wall is a crewmember giving Jason a signal to come on cue.

Visible crew/equipment: As Jason is walking down some steps, a little after he kills J.J., you can see the shadow of a crewmember pushing equipment, cast on the wall.

Continuity: The shards of glass around the porthole change between shots, as Jason attacks Rennie.

Plot hole: How would Jim have been able to get that hockey mask? it even has the replica axe mark from where Jason was hacked in Part III by Chris.

Continuity: After Tamara comes out of the the shower she is completely dry.

Revealing: During the credits, in the shot of the diner, the asian man sitting to the right glances right at the camera.

Continuity: When the blonde girl gets out of the shower right before Jason stabs her with the mirror blade, she exits the shower dry as a bone. She should of been glistening or have water dripping off of her.

Continuity: When Sean is given the present by his father, there is a polystyrene pad next to the computer navigator, which is sticking out. In the next shot it's pushed in neatly.

Factual error: In relation to the position of the sewage workers shadow, and the way Jason kills him, there is no way that the splatter of blood would have hit the wall the way it does. In addition the blood looks like paint.
