Cannibal! The Musical (1993)

Not many people realise that this musical comedy was written, produced, directed by and starred Trey Parker of South Park and Book of Mormon fame. The film was made before the fame of South Park and also featured his creative partner Matt Stone from the show. In the film, the sole-survivor of an ill-fated mining expedition is found guilty of murdering and eating his companions and is ordered to be executed. We then follow his trial as he tells his story through flashbacks, detailing how his taste for gold was transformed into the taste for human flesh. Trey Parker even gave his college professors roles in the film as extras.
