If you want an action-packed motorcycle gang exploitation film, then saddle up to Angels Hard as They Come (1971), produced by king of the drive-in Roger Corman and written by Joe Viola (who also directed) and Jonathan Demme (who co-produced). Three Hells Angels are invited by the Dragons into a hippie commune, and a drunken, drug-and-sex-crazed orgy ensues. The fun ends when one of the hippie chicks is killed; the Dragons blame the Angels and the peaceniks clash with the outlaws. That said, between the heaviness, there are lots of heavy hooters from Janet Wood, Neva Davis, and Becki Cross. Thanks to them, not only the angels are coming . . . hard.
