The opening scene with Laina Mott (Olivia) and Shawn Tellekamp (Kristen) was shot 5 months before the rest of the film was shot.
Jack Stanis doesn't appear in the film until about 35 minutes in.
Overall, this film used over 5 gallons of fake blood.
Jack Stanis states that "this film will answer the question as to who Olivia called at the end of Slash to come and get her."
