Visible crew/equipment: In the finale, Jessica runs over to Jason from behind and she stabs him in the heart with the dagger. Then Jason lashes back and hits Jessica, and she goes flying backwards. Absolutely anyone can see the large blue crash mat that she lands on.

Revealing: When Jason (in Robert's body) is shot in the head at the end of the hall, a close up reveals the bullet hole to be obviously just makeup.

Other: In the scene at the beginning where Phil eats Jason's Heart, you'll notice that he screams like a monster for a bit. Don't you think that the two security guards would hear the screaming, being that they're in the very next room?

Revealing: When the female FBI agent falls over the railing onto the table, you can see that the legs have been pre-bent to make it break easier.

Continuity: There are two times after the female FBI agent gets out of the shower that she is wearing underwear when she put none on, and the pair that she has on is completely different from the one she originally took off. The first is when she runs directly to the door from the shower after the power goes out. The second is seen when she puts on only a towel shortly after, and then falls over the railing, you can see she's wearing underwear there as well.

Continuity: In the scene where they show Jason's mailbox, it says Vorhees. The correct spelling is Voorhees.

Continuity: When the bomb is dropped, Jason is looking skyward, but in the next shot he's looking straight forward.

Continuity: After Jessica shoots Josh in the head, he lies on the floor and his tee-shirt is clearly untucked. But when he grabs Jessica, and then wrestle on the floor, his shirt is now tucked in.

Continuity: In the scene where Jessica is in the shower crying and the power goes out, she gets out, puts on a white t-shirt and goes walking around the house. When she walks through the garage door and grabs a hammer, there is blood on the front of the t-shirt (right at or a little lower than her waist and looks like someone grabbed the shirt with a bloody hand). Where did it come from? She didn't run into anything or anyone. [There's a deleted scene showing her step on a piece of glass. She gets blood on her hands when she pulls the glass out, then presumably wipes her hands on her shirt. Still a mistake, as removing that scene means the blood appears from nowhere, but there's the reason.]

Continuity: When Jason is attacking Steven in Diana's house, before Steve impales Josh (who is possessed by Jason) with the the poker, Josh lifts his head to look into the mirror but the reflection of Jason stays still.

Revealing: In the scene where Deborah and Luke are having sex in the tent, the coroner (as Jason) comes from behind her, stabs her, and brings the poker upward slicing her upper torso in half. If you look closely in normal play, or put in slow motion, you can see the body is already cut before the poker comes up.

Revealing: Jessica is in the shower crying, and then she grabs a shirt and pulls it on, never putting on anything else. However after Steven punches Robert, he carries Jessica to his car. As he puts her down on the seat, Jessica’s shirt rides up, revealing a flesh-coloured thong.

Continuity: When Steven impales Josh with the fireplace poker, Josh starts to stumble very slowly toward the window, but in the next shot, he is moving with enough force to move across the room and shatter through a window.

Continuity: In one inside shot of the tent, Luke is lying down on his chest and he turns the lantern on. In the very next shot from outside, it shows his shadow cast from the inside of the tent, and he is now sitting up.

Visible crew/equipment: When Steven carries Jessica to the car, they climb in. Then, as the shot is being filmed very close to the car, a crewmember wearing a white tee-shirt is perfectly reflected in the car window. It’s so noticeable, it’s unbelievable

Continuity: When Agent Marcus is replacing the burnt bulb while standing on the ladder, between shots the bill of her baseball cap folds itself upward.

Continuity: When Luke and Deborah go into the tent, their shadows show Luke automatically take off the shirt she is wearing. But the next shot, when the camera goes into the tent, Deborah is once again wearing the shirt.

Continuity: At the end of the movie the demons pull Jason down and he is tightly wearing his mask, but the next shot is his mask laying on the ground that Freddy comes back up to get.

Deliberate "mistake": when the FBI agents are shooting Jason, 2 things happen that shouldn't, 1. his machete is shot but doesn't move, the force from the bullet would cause the knife to move. 2. when the bullets hit the knife, they cause sparks, bullets do not spark when the hit metal.

Continuity: When the coroner is inspecting Jason's body he is wearing a watch on his left wrist. While he is eating the heart the watch disappears but returns after he is possessed.
