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)
Revealing mistake: When the main girl finds the decapitated head in the car towards the end, you can see that it's just a doll. (01:09:55)
Visible crew/equipment: At the beginning when the girl is in the mud Jason rams a pole through her head. At the moment when the camera backs up and you see Jason and the girl in the puddle, there is someone's head moving into the picture at the bottom right corner then moves away. You can see a shadow too.
Plot hole: When the sheriff and his deputy find the remains of Roy this is just a few yards away from Darren and Lizbeth's car. It's hard to believe that none of the five people in the paintball game came across the car or the bodies while they were all walking around.
Continuity mistake: When the sheriff first drives into the camp, the red and blue lights on top of his police car change position from shot to shot.
Plot hole: After Jason is "shocked" back to life, Tommy gets into his grave and is trying to get the metal pole out of Jason. During this time, Jason is looking directly at Tommy while he's trying to get the pole out. And Tommy looks right at Jason a couple times, so he should know he's alive, But Tommy doesn't realize he's alive until he grabs him from behind.
Continuity mistake: During the scene where Jason kills Court while Court is driving the motorhome, watch as Jason removes the knife from a sheath on his right side to kill Court. Then, the motorhome crashes and Jason exits. When Jason exits and stands on the motorhome, you can see the same exact knife in the sheath on his right side again.
Continuity mistake: In the film Cort is making out with Nikki in the motor home and his tank top rolls up and it's above his nipples. In the following shot the shirt is rolled back down again. (00:33:45)
Audio problem: Cort turns up the Alice Cooper song, but the volume remains the same. (00:37:40)
