Well it was a comedy musical starring Tim Curry. The plot summary is a young couple named Brad and Janet are going to meet a friend but their tire blew out during a storm. The only place of refuge was a creepy mansion owned by a Dr. Frank N. Furter. When they meet the crazy doctor, who turns out to be a transvestite, he tells them of how he created life, a muscular man by the name of Rocky. It's a really funny movie, kind of a movie that's so bad it's good. I think you can find the movie on Youtube, and if not, you can look up clips.
