1977, Directed by Al Adamson

Oh no! Evil Space Moustache Overlord has outlawed sex! Better sing a few songs and dress up as rabbits, then. That’ll sort things out.

This is certainly the only musical-comedy-sci-fi-softcore-porn retelling of Cinderella I’ve ever heard of. Pity it looks so unamusing, although a lot of that may be down to the incredibly boring voice-over bloke.

Sadly “Hollywood’s Newest Discovery” Catharine Erhardt wasn’t discovered very successfully, as she only appeared in one more film and a single episode of LA Law. But she did star in the infamously perverse porno-horror Through the Looking Glass, so that’s something to tell her grandchildren when they’re over 18.

Favourite bit: The haircuts.
