minute joke "trailer" shown at  Trey Parkers college in Colorado. The cast is largely the same, although  there is no Polly Prye yet, and most of the scenes in the "trailer" are  matched in the final movie, including the songs "Lets Build a Snowman" and  "On Top of You." There are also one or two songs not used in the final movie,  though. In this version Packer, upon seeing the bodies of his mutilated  companions, lets out a loud scream which gradually changes into a musical  note, and he starts to sing a funky number. He sings something similar at the  end of the trailer too. Although in the final movie, characters played by  Matt Stone and Dian Bachar never develop facial hair, this version shows  everyone growing at least a moustache, even Matt. This cheap and amusing  "trailer" is sometimes actually used as the trailer for the final film  [Although the final film does have its own trailer]. The title of the  original trailer  [And the original cut of the movie] was "Alferd Packer: The Musical," but of  course all Troma releases replace the title cards with new ones reading  "Cannibal: The Musical." Versions of the original trailer and the final film  with both titles are circulating somewhere.
