Chatterbox

This movie was a Hollywood legend, passed around from hand to hand for years before video allowed wider distribution as a cult film. It thoroughly lambastes the conventions of movie making, as well as various cliches of pop culture. The late-night TV show that brings the protagonist's vagina (which has at this point learned to sing) on as a guest, with the woman herself just along for the ride standing on a podium with a microphone at her crotch, completely captures the most prurient and soul-destroying aspects of the entertainment machine. What is brilliant about this movie is that it doesn't go crazy on the premise, instead it systematically explores exactly how Hollywood would treat this talking wonder, managing to capture how it treats women in general, and in fact people in general. Yet they keep a deft and light touch, and scene after scene is outrageously funny.
