The British tradition of saucy humor—boobs, bums, and boorish innuendo—is perhaps best exemplified by the long-running Carry On movies. But there is also a nearly forgotten genre of even saucier X-rated movies. Coaxing the facts from previously reluctant interviewees, Simon Sheridan has compiled the first definitive filmography of this long-overlooked genre, complete with an expanded filmography and rare and previously unpublished stills. The result is the often funny, sometimes tragic, but undeniably revealing story of a bygone era.
