Director: John Waters
Running time: 82 minutes
Where you can watch it: YouTube

Why it's unavailable: As is the case with Mondo Trasho, Multiple Maniacs isn't available because of music clearance issues. Like experimental bretheren Kenneth Anger, Waters loves him some illegally acquired rock and roll.

Why you should watch: Because of Lady Divine's Cavalcade of Perversions—yes, Multiple Maniacs follows a freak show, an obvious touchstone for Waters's warped interests, and though the results are uneven, the high points rank among his filthiest. See, for instance, the Puke Eater. This film also saw Waters stitch up his core group of actors. Watching them gel is a gross treat.
