Corrected entry: 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.
Corrected entry: 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.
Corrected entry: When Edna is watching the news, the newscaster says that, "Bodies were found literally strewn over the four square mile campground." However, Jason brought most of the bodies to his cabin in the woods.
Corrected entry: If there have been multiple killings at Camp Crystal Lake and everyone, even the police, knew about it wouldn't they have closed it down for good by now?
Corrected entry: When Chris and Rick go out to the van after the group arrives, she notices that the van's side door is open and she wonders aloud if it was closed earlier. She then reaches in and Shelly grabs her wrist, startling her. Where did he hide in the van that she couldn't see him? There is nothing big enough for him to hide behind.
