Saucy! Secrets of the British Sex Comedy

In the first episode, actor Robin Askwith reveals how Confessions of a Window Cleaner became the most successful home-grown movie of 1974, inspiring dozens of copycat titles and making his backside the most famous in British history.

The second part of this two-part documentary explores how X-rated movies entered the mainstream, despite the protestations of Mary Whitehouse, and reveals the tragic story of actress Mary Millington. The programme also reveals how the advent of home video and an explosion of the availability of cheaply made pornography eventually brought the cinema sex industry crashing down, even as it approached respectability.
