It's a shame that Claudia Jennings, Playboy playmate of the year, died at age 29 from a traffic accident, and made a series of low budget, forgettable films. Many of these films still appear on TV from time to time, but not Unholy Rollers, her best film. Another shame. Unholy Rollers is about Claudia joining a roller derby troupe and because of her personality and strikingly good looks, never being accepted into the group. The film is low budget all the way. Probably did well at drive-ins and rural markets, but got swamped by Kansas City Bomber released the same year. I never cared for the roller derby, it's quite stupid, but this "inside story" is quite decent. Just don't expect to find it.
