The film was directed by series creator Trey Parker, who co-wrote with series co-creator Matt Stone and Pam Brady. It stars Parker, Stone, Mary Kay Bergman, and Isaac Hayes, all of whom reprise their roles from the series, with George Clooney, Eric Idle, and Mike Judge in supporting roles. The plot follows Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick as they sneak into an R-rated film starring the Canadian comedy duo Terrance and Phillip, after which they begin swearing.
