This was originally two short films that were put together to make a feature film. Part one was inspired by the Friday the 13th (1980) films (filmed in 2000), and part two was inspired by the movie Scream (1996) (filmed in 2001).
The last day of filming (principal photography) was delayed by over two months so Marc James Beauchamp (Clay) would have time to recuperate after injuring his ankle in a drunken skateboarding accident.
During one of the nights of filming, Annie Julian (Kaya) choked herself unconscious in the scene where she's attacked by the killer. That shot was left in the final cut of the movie.
