Revealing: In the scene where Linderman dashes at Jason and impales him with an American flag, Will is dragging Lori (who is supposed to be unconscious). He's dragging Lori by her arms... but when he suddenly reaches behind his back with his right arm, her right arm stays up in the air.

Revealing: When Freddy and Jason are fighting towards the end of the movie, Freddy cuts Jason's fingers off so he drops his machete. But when Freddy catches it you can easily see that it isn't a real one (its made of rubber, or something like that).

Revealing: When Jason throws Linderman against the wall, if you slow it down, you can see that the person Jason throws looks nothing like Linderman, it is OBVIOUSLY the stunt double.

Continuity: When the teens enter the mental institution to get the dream suppressant drug, it shows a security guard drawing his pistol in alert to an intruder banging on a door. The next shot cuts to show the response of two teens hearing a single shot fired, and then cuts back to show the security guard under the door with four big dents from Jason and two bullet holes. The holes are located at the top right hand corner of the door and the other near the door handle.

Revealing: As soon as the drunk kid sets Jason on fire there's a few quick shots of Jason's face but there's a perfect hole right through his head where his eye is supposed to be and you can see the night sky through it. Some people say it's a reflection off the goggles to protect the actor from the flames. Either way it's a mistake.

Continuity: When the girls are at Lori's, just after Kia asks them if they think she needs a nose job, the lights flicker. When they flicker Kia is holding a compact in her left hand and she begins to close it. Both hands are up by her face but then the angle changes to a wider shot and her left hand is empty and on her lap and the compact is in her right hand as she places it on the sofa.

Visible crew/equipment: In the dream fight between Freddy and Jason, you can see the wire that holds the machete up when Freddy catches it after Jason swings it.

Continuity: When Lori explains she haven't had much sleep lately, Kia says "Lori, you had to sleep at the police station.". If you look at Kia's purse's straps you can see some of Kia's dress sticking up between the straps. When it cuts the piece of her dress no longer sticks up between the straps.

Continuity: After they have sedated Mark the institution guards throw him on the bed, and we see him landing on the pillow. Two shots later he is off the pillow.

Continuity: At school when Lori approaches Will, she puts her hand on his chin. Will then places his hand on Lori's hand and says "I thought you might be in trouble," while their hands still are on his chin. When it cuts, their hands are suddenly down.

Continuity: When Jason throws Linderman to the wall he gets impaled by a sharp object stuck to the wall. However as Linderman is flying against the wall before hitting it the object isn't there.

Continuity: When Freddy and Jason get hit by the cart at the construction site, they land next to each other on the dock. But in the next shot, we see Jason getting up quite a distance away from Freddy.

Continuity: When Mark tells Kurt he never does checkers, we see Will holding his hand down on the table. When it cuts he has his hand up by his chin.

Continuity: In the scene when Kia and Gibb meet Lori outside on the school bench after Trey's death look a few moments later, you see a close up shot of Gibb putting the cigarette towards her mouth and almost reaches her lips, in the very next shot Gibb has the cigarette down in her hand and then a second later she then puts it to her mouth.

Continuity: When the guards leave after sedating Mark, Will gets up in his bed and we see Will's pillow askew. When it cuts his pillow is straight.

Continuity: When Mark turns up at school telling about Freddy to Lori, as he says "Then he came back" we see Lori pulling her hair back with her hand without lowering her hand. When it cuts, her hand is suddenly down.

Continuity: In the boiler room in Jason's "dream", the container that pins Jason to the floor lands directly on top of him. However, in the close-up of it still pinning him down, you see Jason's upper-body sticking out to the side.

Continuity: The end of Jason's machete changes throughout the whole movie. Sometimes it has a rounded end, sometimes it has a pointed end and so on.

Plot hole: The sheriff orders a 24 hour roadblock on the town, yet the van has no trouble driving to Crystal Lake.

Continuity: In the fight scene on the pier, just after Freddy has sliced off Jason's fingers, Jason blocks the machete, Freddy slashes him with the glove and then cuts Jason's chest with the machete and raises the machete for a downward blow. They are now standing face to face. However, when Freddy makes this cut, Jason's back is all of a sudden turned, enabling Freddy to cut his leg from behind. There was no time for him to turn around between cuts.
