Continuity: When Debbie is killed in the hammock, in all shots of her, the quilt covering the hammock net has patterns sown on it, such as flowers. However, in the closeup of Debbie as the knife comes through her chest, the quilt covering the hammock is the same one as before, however you can now see it is suddenly the other side of the quilt.

Continuity: When Chris knocks Jason out with the shovel, the position of unconscious Jason's legs changes between shots.

Visible crew/equipment: In the scene where the snake leaps out the cage you can see a dodgy looking fake snake attached to a wire spring.

Continuity: At the end of Part 2 Jason was unmasked, showing long hair and heavy eyebrows. In Part 3 he's unmasked again, but he looks totally different. He has some hair but is mostly bald. His face looks horrible, as his eyes don't line up, his skin is grayish, etc. Part 3 was supposed to have happened the day after 2, and yet he is now bald and his features are even more distorted.

Plot hole: Jason somehow manages to get the two halves of Andy's dead body on the wooden ceiling rafter, with no blood dripping onto the hammock and staining it, or getting none onto the floor. Debbie then gets into the hammock, and about a minute later, blood starts dripping - for no apparent reason. Why?

Continuity: When Chris shows Debbie the hammock, between shots the way the net hangs and the position of the net changes.

Visible crew/equipment: When the kids first arrive at the camp, as the camera pans as the van pulls up you can see a little bit of a white screen, a small bit of the camera and the top of a crewmember. It's clearer in the blue strip of the van.

Visible crew/equipment: After Vera says "uh-oh," as her and Shelley sit in the car outside the grocery store, the camera pans around to the side window. You can see a hooded cameraman reflected in the small triangular window, as the camera pans.

Continuity: When Harold feeds the fish, in wideshots there is a note next to the fishbowl which reads "Say Hi to..." However in the closeups of the fishbowl, the note has gone, and should be visible.

Continuity: Jason approaches Loco with a pitchfork with five prongs, but the pitchfork that enters Loco's stomach has only four prongs.

Continuity: An error between Part II and III. In part two, Ginny hits Jason with the machette through the shoulder and through his chest. There is a scene later at the end of Part II where Jason, unmasked, crashes through a window and the machette is still in place in his chest. This contrasts with the shot in the beginning of Part III where he "comes back to life," but in Part III the machette is not in his shoulder but in his hand.

Continuity: During the scene in the car outside the grocery store, the number and position of tyres on the metal tire rack standing near the beer lorry changes.

Visible crew/equipment: When Loco, Fox and Ali stand by the van before they steal the gas, the long black boom pole is clearly reflected in the back window of the van.

Continuity: When Chris runs into the bedroom away from Jason, there is a long decorative picture hanging to the left of the window, and between shots a long piece of brown string, hanging down the painting, alternatively appears/disappears.

Visible crew/equipment: When Chris is on the wooden beam in the stable, as she jumps down to land on Jason you can see a safety wire to the bottom left of the screen.

Revealing: When Debbie is in the shower and we see a shot of her through the shower curtain, you can see she is wearing white underwear.

Continuity: When Chris stabs Jason's hand, she stabs his right hand. In the shot of Jason coming downstairs, after Chris has jumped from the window, his left hand is all cut and bloodied for this shot.

Continuity: When Chili walks into the kitchen while Chuck makes popcorn, the pan goes from on the stove to on the table between shots.

Visible crew/equipment: Loco finds Fox swinging on the rope hanging from the top of the barn. He tells her to get down. In the next shot, we see the rope still swinging, but Fox has vanished. If you look in the bottom right of the barn, you can see the leg of a crewmember moving.

Continuity: When Shelley runs and stops Vera in the car, to ask if he can go with her to the store, the car is in sunlight. In the next closeup, as she drives off, it is in complete shade.
