Continuity mistake: When Andy is cut in half by Jason, blood spurts everywhere. However when Debbie gets out of the shower and she walks through the same area and there is no blood anywhere for her to notice. Jason didn't have enough time to clean up the area. (01:00:15)
Continuity mistake: When Jason swings the machete to kill Andy, he swings vertically, which would have cut him between the legs down to his head, as he was walking on his hands. Later when Andy is shown, he is cut horizontally at the waist. (01:00:15)
Suggested correction: This is wrong. It might look it at first, but if you pause it, he's cut vertically and his legs are simply stretched to be able to put the feet by his head. The cut reached just past his abdomen, so Jason spread Andy's legs to fit on the rafter, giving the illusion that he was cut in half horizontally.
Hogwash. I saw this scene and Andy was cut vertically, not horizontally. There is no illusion. Everything is too obvious.
That's what I said, vertically. The shot is quick, which is why some people think he's cut horizontally.
Revealing mistake: When Debbie is in the shower and we see a shot of her through the shower curtain, you can see that she is wearing white underwear. (01:00:20)
Continuity mistake: When Debbie is in the shower, as the camera pans towards the shower, you can see the towel hanging up and her bathrobe hanging over the towel. However when Debbie pulls the shower curtain back, the towel is now hanging over the bathrobe. (01:00:35)
Continuity mistake: After getting out of the shower, Debbie still has her silver necklace on. She leaves the bathroom and the necklace has disappeared. (01:01:15)
Other mistake: The whole time Debbie is in the shower, she only washes her chest, arms and stomach. She's always mostly just washing her arms over and over. (01:01:25 - 01:03:45)
Continuity mistake: The magazine Debbie reads in the hammock changes - look at the back cover when she climbs into the hammock with it. When she turns a page, watch closely and look at the back cover. It has changed. (01:02:05)
Continuity mistake: 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. (01:02:25)
Revealing mistake: When Debbie is in her hammock, she looks up to see Andy who is dead. However you can see his hand moving. (01:02:25)
Continuity mistake: When Debbie is killed in the hammock, the knife goes through her breast. Later, when Chris pulls the knife from her, the knife is suddenly in her neck. (01:02:25 - 01:13:55)
Continuity mistake: When Chuck makes the popcorn the amount of popcorn in the pan and around the stove differs. (01:02:50)
Continuity mistake: When Chili walks into the kitchen while Chuck makes popcorn, the pan goes from on the stove to on the table between shots. (01:03:00)
Continuity mistake: Chris puts her lantern down on a table in the sitting room, before going upstairs and finding the flooded bathroom. Later when Rick's body is thrown through the window, the lantern has vanished. (01:08:30 - 01:12:25)
Factual error: Jason picks up a red hot poker from the fireplace and it sizzles. Fire pokers only sizzle if they touch something. (01:08:56)
Visible crew/equipment: When Jason crushes Rick's head you see the wire pulling his eyeball out. (01:09:10)
Visible crew/equipment: When Jason crushes Rick's head, it is clear the head is made from wood and the fake head is resting on metal shoulder frame. (01:09:10)
Continuity mistake: When Chris is in the sitting room, Rick's body is thrown through the window. When Rick lands on the floor a shard of glass slides down and lies on his cheek. In the next shot it's gone. (01:12:10)
Continuity mistake: 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. (01:14:05)
Continuity mistake: When Chris comes out from the green door waving a knife at Jason, the green door closes all the way behind her. It cuts to Jason and then back to to Chris, and behind her in the background the green door is now wide open. (01:14:10)
Revealing mistake: When Jason throws a knife after Chris you can see the wire attached to the knife. (01:14:25)
