When the movie was selected, none of the writers had watched the entire thing. While writing for the episode, they saw the entire movie for the first time, including the graphic rape and murder scene halfway through. Shocked, the writers edited the entire scene out of the episode. After that, movies being considered for the show had to be watched in their entirety before they were selected.
This episode is on the Volume 3 DVD Box Set of Mystery Science Theater 3000.
Another name of the riffed movie is Five the Hard Way (1969).
