Orgazmo (1998)

Joe Young is a struggling Mormon actor from Utah who begins preaching the word of God in LA to little success. He stumbles upon the set of an adult movie directed by the famous Maxxx Orbison and it doesn't take long for him to spot Joe as the leading man for his new effort "Captain Orgazmo." Joe's upbringing and conservative fiancee, Lisa, raise potential problems, but when Maxxx promises big bucks -- and a stunt penis to replace him in the hard-core scenes -- Joe agrees. Joe's sidekick in the movie is Choda-Boy, an engineer with a PhD from MIT and the inventor of the Orgazmorator, a raygun which emits a light beam that stuns its victims with the most intense orgasm they have ever experienced. "Captain Orgazmo" becomes a huge success, with Joe praised by audiences and critics worldwide. All's well until Lisa suddenly shows up from Utah and accidentally sees the movie at a video store.
