Biker movies were aimed at teenage audiences and the drive-in crowd. The genre took off in the 1960s when the real world Hells Angels received much media attention. Hollywood cranked out dozens of low-budget exploitation outlaw biker movies during this decade. Novelty movies of the genre featured all-female gangs, horror and zombie crossovers, and one featured a gay gang. The biker outlaw genre played itself out in the 1970s.
