This was the last film to be shot at Roger Corman's studios in Venice Beach, California, and it only had a 12-day shooting schedule. The studio was being torn down during the production, which they wrote into the script.
Though the principal photography took place in February 2001, the final sequences were not filmed until July 2002. The long break was necessitated by the fact that the scenes were to be shot in Malibu, but the rainfall was unusually heavy, so the completion of the film was postponed. Director Brian Katkin actually shot another film during the break in this movie's production.
The film actually began life as a remake of The Slumber Party Massacre (1982), and writers John Huckert and Dan Acre were hired to pen the script. But after visiting the soon-to-be-demolished studio they came up with this idea instead. Producer 'Damien Akhavi' helped them write the story. Footage from the original 'The Slumber Party Massacre' can still be seen during a murder sequence as an inside joke for the production crew.
