Roller Derby was the perfect spectator sport. What other athletic endeavor regularly featured fearsomely fit females flinging their helmets aside and flailing at one another with the intention of tearing off one another’s jerseys? Roller Derby’s gladiatorial popularity peaked in the early 1970s, and Unholy Rollers (1972) was right there to ride the crest. Looking every inch like the former Playboy Playmate of the Year that she was, flaxen-tressed knockout Claudia Jennings took top billing as a factory-worker chick who strapped on her skates and raced for glory, pausing only for pleasing bouts of gratuitous violence and lesbianism.

Skinfo: Roller Derby's inspirational value cannot be overstated. Unholy Rollers is actually the lesser-known of two spectacles based upon the wheeled phenomenon in 1972. Whether justly so or not, Kansas City Bomber (1972) with Raquel Welch seems to have stuck best in the imaginations of fans who love battling broads.
