The Unholy Rollers (1972) -**** The great thing about exploitation movies is that no trend, no matter how short-lived or culturally insignificant, is safe from them. You expect exploitation movies about rock and roll, drag racing, biker gangs, hippies, drugs, punk rockers, and that sort of thing, but roller derby?!?!
A serviceable melodrama set in the world of roller derby, In lieu of a fully realized storyline, Unholy Rollers is a fairly typical Roger Corman production in that it blends sex, violence, and an underdog antihero. For the most part, the picture avoids outright exploitation elements, so it makes for comparatively guiltless viewing.
