Rented Lips(1987)

A documentary filmmaker, who has spent the last 15 years making films like "Aluminum: Our Shiny Friend," is finally given the chance to make the documentary on Indian farming he has always wanted to. The catch? He must simultaneously direct a porn film. But as he tries to make the porn film, which he turns into a musical called "Halloween in the Barracks," he must deal with a temperamental actor, a fundamentalist preacher, and other obstacles.
