Writer/director Adam Rifkin had a dream, working to bring "The Dark Backward" to screens. However, he also needed work as a young filmmaker, and part of his learning process involved the creation of 1990's "The Invisible Maniac," which was written and produced in a matter of weeks. It's a low- budget quickie from Rifkin (billed here as "Rif Coogan"), and his creative mission here is to play with the mad scientist genre and photograph as many nude actresses as possible. Even with limited creative goals, "The Invisible Maniac" isn't quite the romp it should be, as Rifkin has a real problem with filler, noticeably sweating to get the movie up to a sellable run time, which results in some serious drag in a feature that wants to be a rip-roaring ride of violence and sexploitation.
