Cannibal! The Musical (originally known as Alferd Packer: The Musical) is a 1993 American independent black comedy musical film directed, written, produced, co-scored by and starring Trey Parker while studying at the University of Colorado at Boulder, before reaching fame with South Park alongside his friend Matt Stone who also stars in and produced the film. It is loosely based on the true story of Alferd Packer and the sordid details of the trip from Utah to Colorado that left his five fellow travelers dead and partially eaten. Trey Parker (credited as Juan Schwartz) stars as Alferd Packer, with frequent collaborators Stone, Dian Bachar, and others playing the supporting roles.

Cannibalism is the act or practice of humans eating the flesh or internal organs of other human beings. A person who practices cannibalism is called a cannibal. The expression cannibalism has been extended into zoology to mean one individual of a species consuming all or part of another individual of the same species as food, including sexual cannibalism.
