Continuity mistake: During the scene where Jason kills the couple in the volkswagen and again during the police chase it goes from night to day to night again. (00:13:00)
Continuity mistake: The propeller damage to Jason changes between shots. (01:18:00)
Continuity mistake: In Part V the mayor says Jason was cremated, which would mean there would be no body to "bring back" for this film.
Continuity mistake: Jason's machete disappears from his hand as he walks after Steven through the woods.
Continuity mistake: The sheriff shoots Jason in the head with his revolver and makes a hole by Jason's right eye. Jason pulls Tommy underwater and begins to choke him and Tommy passes out. There is a close up of Jason's face and the bullet hole is now gone. When Megan tries to save Tommy she cuts Jason's throat with the boat propeller and the bullet hole is visible again on Jason's mask. (01:07:25 - 01:18:00)
Continuity mistake: There is shot of the car turning hard to the right that doesn't belong here. It's part the upcoming shot when Megan hooks the wheel and skids to a stop in front of her father. You can see the red light from her fathers police car on the front end and side as it turns. She is not on Cunningham road yet. Also, the driver of the car appears to be a man with a moustache wearing a blonde wig. (00:51:25)
Continuity mistake: After Tommy begins reading the book the next shot of Jason walking doesn't belong there. It is part of shot from later in the movie after Sheriff Garris shoots Jason in the head. The bullet wound and the blood from the head crush kill are visible on the mask. (00:43:13)
Continuity mistake: When Megan talks to the girls there are multiple girls in this scene who are never seen again in the movie. There are 2 black girls and at least 3 white girls who are never seen again. Also, the main little girl from the later parts of the movie is nowhere to be seen in this shot. (00:27:26)
Continuity mistake: Sissy put 2 ketchup bottles and 1 mustard on the counter top. When she turns to listen to Megan she bumps one bottle knocking over both ketchup bottles. As Megan finishes her story she points to the arriving bus full of kids you can see both bottles are back upright and the second ketchup bottle has moved behind the mustard. (00:19:10 - 00:19:45)
Continuity mistake: Hawes' heart is missing from where it should be beside the grave. When Jason heart punched Hawes he dropped the heart as Hawes fell back into the grave. As Jason turns he can be heard stomping on the heart. The heart may be squashed but it should be there and the caretaker should have spotted it. The broken shovel and gas can are also nowhere to be seen. (00:17:58)
Continuity mistake: The headlights from the cop cars that were right on her tail are now gone and the road behind the car is dark when she hooks the right on Cunningham Rd. In one second the cops have fallen so far back it takes them more than ten seconds before they pull into frame. (00:51:52)
Continuity mistake: In this scene where Jason grabs Sissy he grabs her by her shoulders, but the next shot when he pulls her out the window his left hand is on her neck and his right hand is between her legs. This was the only way Jason could pull her through the window without her lower body slamming into the window frame. (00:49:00)
Continuity mistake: The position of the Lemon Brus can beside Sissy's bed changes. In the first shot it's turned around backwards facing the box behind it so you can only read Lemo. In the next shot where Sissy grabs the can the label is facing the camera and you can read the entire label Lemon Lime Brus. (00:46:38)
