The movie was originally intended to be R-rated, but after the success of 2008's Prom Night (2008) remake, Summit Entertainment planned to trim it to a PG-13 rating. However, the studio changed its mind, and decided to keep the movie as a solid R-rated movie.
Leah Pipes originally read for the part for the character of Ellie. After auditioning for Ellie, she auditioned for the part of Jessica. After a second audition for the role of Jessica, as well as a makeover of hair extensions and a wardrobe change, she was given the part.
In August 2009, the British Board of Film Classification originally classified this film as '18', meaning that no one in the UK under 18 years of age would be able to see it. E1 Films (the UK distributor) asked the BBFC to reconsider, and in a rare move, it decided to pass the film uncut at the lower '15' category instead.
