The Invisible Maniac, known in some circles as The Invisible Sex Maniac, is a 1990 American Horror-comedy written and directed by Adam Rifkin. It's about a young boy who gets caught by his mom checking out a naked lady with his telescope and gets lectured by her on the evils of women. Twenty years later, he announces his theories of invisibility, and gets laughed at by his fellow scientists... and so he responds by killing four of them. He escapes from the mental hospital and gets a job teaching summer school physics at a high school. The students decide to start teasing him just as he perfects his invisibility serum and, well, you can guess where it goes from there. Join Scotch and Bob Harris as they dissect the subtleties of this early 90's cult-classic in this week's B-Movie Bonanza.
