S1 Ep4 The Keys of Marinus

First broadcast from 11 April to 16 May 1964 the gang are tasked with searching for four keys to restore the Conscience of Marinus, a computer which maintains law and order.Here come the Voord, the absolute fashionistas! We join the gang in their version of the Crystal Maze. Will you start the fans please!

David spots some of the classic Billy Fluffs, enjoys the lovely legs on show, and teaches Sarah about film editing thanks to a pair of oversize flippers.

Sarah has a rant about silly doors and silly hypnosis but copes a bit better with yet more screaming, this time from plants as well as people!

We love suspicious Ian, whose affections won’t be bought, and the Doctor as the Lawyer. And we laugh about The Brains Trust and the smallest rope bridge you’ve ever seen.

Firsts: missing story, Hartnell holiday, “Let’s split up!” and BBC2 as a competitor
