Cannibal The Musical opens February 10th at the Panasonic Theatre in Toronto for a 3-week run. Trey Parker originally wrote, produced, co-scored, directed and acted in the musical as a film, prior to co-creating South Park and The Book of Mormon with regular collaborator, Matt Stone. Loosely based on the true story of Alferd Packer and the journey from Utah to Colorado that found Packer’s fellow travellers inextricably dead and partially eaten, the movie has since been adapted for the stage with new jokes and songs, and is now launching its world premiere.
