Revealing mistake: Near the end when Jason throws the hammer at the girl, it sticks to the damaged part of the wall after it hits. But it's just against the wood with the flat top, there's nothing to hold the hammer there and it's only hit the wood on the other side of the wall. They probably used a magnet to attract and keep it there for safety reasons. (01:15:00)
Continuity mistake: When Trish and Tommy push the cupboard in front of the door, the figurines and items on the shelves move/fall off/reappear between consecutive wideshots and closeups. (01:15:10)
Continuity mistake: When Tommy and Trish are hiding in a room, they sit down on the floor and Tommy grabs a chair in front of him. When it cuts the chair lies on the floor. (01:15:25)
Continuity mistake: As Jason breaks into Tommy's room, a purple monster mask on Tommy's wall starts to spin, then stops a few shots later, then starts spinning again in the next shot. (01:16:00)
Continuity mistake: When Trish grabs the TV to hit Jason with, the big lamp gets knocked to the floor. Moments later as they leave the room, the lamp is back up to standing. (01:16:20)
Continuity mistake: After electrocuting Jason with the TV, he falls backwards, and the door is left open. When Trish and Tommy walk over, the door is shut. (01:16:25)
Continuity mistake: When Trish is inching by Jason lying on the floor, in one shot she steps over his arm and her feet are near his shoulder, then in the next shot it shows her stepping over his arm again. (01:17:10)
Revealing mistake: When Jason rips Jimbo from the door, it shows a close up of his hand. Looks and tears like rubber. (01:17:15)
Plot hole: When Jason is going next door to chase after Trish, he pulls Jimbo's body down from the doorway and begins walking towards Trish's cabin. He is seen walking by himself. However in the next scene, he throws Rob's body through the window. There was no time for him to go back and get the body. (01:17:15)
Revealing mistake: Just before Trish jumps out of the window, as Jason runs forward to get her, you can see that he has normal, human eyes, instead of his disfigured, strange eyes, seen at the end of the movie. (01:18:00)
Revealing mistake: When Trish jumps out the window and falls to the ground you can see her using a body suit covering her from her hips and down her legs. (01:18:15)
Revealing mistake: When Trish jumps out through the window, rolls off the deck, and lands on the ground below, she obviously lands on a mat or some other protective device covered to look like mud. It jiggles like jelly in a perfect square when she lands on it. (01:18:15)
Continuity mistake: After Trish jumps out of the window, the position of her feet and legs, and the planks of woods around her, change between shots. (01:18:15)
Revealing mistake: When Trish has entered her house after escaping from Jason, she hears him behind her in the doorway, and swings at him with a machete, but hits the door frame. You can see there's a mark from a previous swing. (01:19:20)
Continuity mistake: Trish swings the machete at Jason, and knocks his mask off. In a behind shot she holds the machete with both hands. In the next shot she only holds it with one. (01:21:05)
Continuity mistake: When Trish drops the machete it falls half ways on a carpet. When Tommy picks it up it lays on the floor. (01:21:15)
Revealing mistake: Trish jumps out the window and lands face up on the ground. You can plainly see it's Kimberly Beck's stunt double. She looks nothing like her. (01:21:35)
Continuity mistake: After Tommy slices Jason in the head with the machete, he picks the machete up, and in this shot his shirt is dry. In the next shot when Trish goes over to hug him, his shirt is wet, then dry again. (01:22:00)
Revealing mistake: Near the end when Trish is running from Jason, Jason crushes a lamp on the floor and for an instant it becomes pitch black. A moment later, the room is lit again by a sudden occurrence of "moonlight." (01:23:15)
Continuity mistake: Trish swings the machete overhanded, but in the next shot she knocks Jason's mask off underhanded. (01:24:25)
Answer: You can see from the inside of the house Gordon jumping through the window by himself. It shows him jumping on the table then through the window.
