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.

Visible crew/equipment: In the scene where Lori wakes up in the police station and follows the dropping blood, she turns a corner because she hears a little crying. Right after she turns the corner, the cameras show office windows. You can see someone sitting down and a cameraman on his knees.

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 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.

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

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 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.

Continuity: When Freddy, disguised as Mark's brother, approaches Mark saying he's gonna send them a message, the dirt on Mark's face differs between the shots.

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 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.

Continuity: On the deck, after the girl flashes, the way she holds her top to cover her cleavage changes between shots.

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 Jason crashes through the cabin wall and slashes the teen, a crate on Jason's right foot alternates from being on / off between shots.

Continuity: When Lori, Kia and Gibb meet and they hug each other, we see Kia putting her arm on Gibb's shoulder. When it cuts Lori's hand is on Gibb's shoulder and Kia's hand is on Gibb's back.

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: 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: 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.
