From Wikipedia:

The Residents had begun a movie in 1972 called Vileness Fats. The concept of the movie was to shoot it on a new media form (reel-to-reel video) and tell most of the story through music. The story itself was about a village under siege by bandits stealing the meat supply, forcing the population to exist on vegetables. Unbeknownst to the population, the leader of the bandits is their own spiritual leader. To take care of things, the village hires Siamese twin tag-team wrestlers to be their saviors. Unfortunately their saviors also have other problems, including an Indian princess whose lovers always die.

The film itself, despite over 14 hours of footage, was never finished. In 1984 it was edited to approx. 32 minutes and released on a VHS videocassette titled Whatever Happened to Vileness Fats?; the companion soundtrack was also released the same year. Another re-edited version (approx. 17 minutes) of the footage was released on the Icky Flix DVD in 2002.
