The Invisible Maniac 4K 1990

Why is it that insane, sexually-repressed geeks are the only people who seem to learn the secret of invisibility? A nerdy scientist goes mad and kills some of his colleagues. Why? Cause they laughed at him and his failed invisibility experiment. He soon escapes from an asylum and gets hired as a high school physics teacher. He's teased by several vixens in one of his classes. This inspires him to perfect his formula. Despite being injected into his bloodstream, the serum affects his clothes and eyeglasses (how convenient). Once invisible however, all he can think of is to hang out inside the girls' locker room. After his secret is discovered he goes on another senseless killing spree. 

If 700 monkeys were pecking away on 700 computer keyboards for 700 years, one of them might come up with Shakespeare's "Hamlet." It would only take about five days however, for a dozen of them to come up with "The Invisible Maniac." This movie is unimaginably silly and stupid with gratuitous nudity its only redeeming feature. By comparison, it makes other invisible man schlock like "The Amazing Transparent Man" seem worthy of a best picture nomination at the Academy Awards. Then again, you know you're in trouble when the theme song playing during the closing credits is the best thing about the movie.
