I Know What You Did Last Summer (1997)

Continuity mistake: After Barry has jumped into the water reclaim the crown, he comes out of the water with a perfectly clean shirt, but in the next shot the blood is back on his shirt as expected. (00:22:50)

Continuity mistake: Max lies dead in Julie's car covered in crabs. He was hooked very deep under his chin, yet when we see him, the wound is gone. (00:59:15)

Plot hole: Barry gets killed violently at the pageant. So obviously there should be blood everywhere. When the police go up to the crime scene, they find nothing. There's no way the killer had time to clean up anything, let alone drag away Barry's body without someone seeing him. And blood starts dripping after the police leave the scene.

Trivia: When the kids are on the beach arguing about the urban legend it is this one - http://www.snopes.com/horrors/madmen/hook.htm - that Ray is trying to relate. (00:10:00)

Trivia: Believe it or not, this movie is loosely based on a mystery novel from the 70's.

Trivia: Max (Johnny Galecki) was killed to beef up the body count. The scene was filmed after principal photography.

Officer David Caporizo: Oh, and did this killer use his hook to cut all your hair off?
Helen: No, he used scissors, asshole.

Barry: We did a lot of things last summer.
Julie: Yeah, well, only one murder comes to mind.

Ben Willis: You in some kind of trouble child?
Julie: Yes, yeah I'm in a lot of trouble.
Ben Willis: That's a shame, being that it's the 4th of July and all. Kids like you should be out having fun. Drinking, partying, running people over, getting away with murder... things like that.
