Continuity mistake: When Jessica stabs Jason, black blood squirts over his hockey mask, but in the next shot it has gone. (01:20:25)
Continuity mistake: 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 mistake: When the bomb is dropped, Jason is looking skyward, but in the next shot he's looking straight forward.
Continuity mistake: 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 mistake: Jessica's baby changes from one scene to the time she arrives at her moms house. First, the baby doesn't have much hair. Then at the house, her hair is thicker and she seems to have grown a little.
Continuity mistake: When Debbie is in the tent with her boyfriend, she gets a condom out of the wrapper and throws it aside, still in the tent. Later on, the wrapper is outside the tent, because we see Jason step on it.
Suggested correction: We see her toss it. Don't see where it landed. Could have easily gone out the tent flap.
Continuity mistake: The father of Jessica's baby, while in jail, had some of his fingers broken by Craitan Duke, but in the next scene, he is fighting another character and his hand with broken fingers is working fine.
Continuity mistake: When Steven fights the possessed sheriff at Diana's house, they hit the table knocking the lamp on the floor. You hear it shatter yet it's still lit.
