Continuity: 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.

Continuity: 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.

Visible crew/equipment: When Julie comes home at her mothers house, she looks at her diplomas on the wall. When her mother comes in the room, you can see a reflection of a boom mike in the frame behind Julie.

Visible crew/equipment: When Helen is being chased by Ben, she runs to "Shivers" and up to the glass door, screaming "Elsa!" In this shot you can see a crewmember reflected in the glass door.

Factual error: When Helen and Julie are researching David Egan on her computer, the browser shows the URL as '//http:cnty457.lib.org'. It should of course be 'http://cnty457.lib.org'.

Deliberate "mistake": The film supposedly took place in the Coastal Carolina region. This is a geographically flat area, called a coastal plain. In the beginning of the film, the kids were driving along ocean cliffs, which are not present in the Carolinas. Obviously, this was filmed in California.
