Before there was South Park, there was Trey Parker's hilariously maniacal musical comedy masterpiece, Cannibal! The Musical. Starring Parker and South Park co-creator Matt Stone, the film is based on the legend of Colorado Cannibal, Alferd Packer. Cannibal! The Musical tells Packer's version of what really happened when he and a group of gold diggers embarked on their fateful trip into the Rocky Mountains. Gruesomely gory, savagely satirical and painfully funny, Cannibal! The Musical stands as a predecessor to what would come next for Parker and Stone, and features several trailblazing jokes that would become part of the South Park legacy!
