Secrets of Sex

The film comprises a set of episodes, each featuring recurring sexual themes depicting the battle of the sexes, and introduced by an Egyptian mummy voiced by Valentine Dyall.

The episode of the monster baby is a bore, but the single shot of it, at the end is brilliant.”[3] Released in February 1970, it was a huge success in the UK, running for six months at the Jacey Cinema in Piccadilly Circus alone, during which time it recouped its entire production cost.

… it's sad that censorship should function against its own long term purpose and re-enforce the man-in-the-mac’s sexual furtiveness by denying him the chance to view sex irreverently.

In January 2010, the film, under its original title, was finally released on DVD in the UK by Odeon Entertainment, featuring new sleeve-notes by author Simon Sheridan.
