From the boys behind the "Saw" movies comes "Repo! The Genetic Opera," a wacky musical about a mainstream market for human organs where people are buying, selling and upgrading their body parts. One of the stars of the film is none other than Paris Hilton, who we interviewed recently along with director Darren Lynn Bousman. Read about our full chat with Hilton during our visit to the film's set here. For a taste, check out the clip below in which the actress says her character's song "Come Up and Try My New Parts" is almost a hard-rock single.
