"If you'd had your shoes on, my boy, you could have lent her hers!"

Well, the new Matt Smith series is upon us and, never ones to be accused of having their fingers on the pulse, Jim and Martin head back to 1964 to take a look at the William Hartnell classic, The Keys of Marinus! Along the way they discover google-eyed brains in jars, a trouserless young man, a sex-starved hunter and clumsy flipper-footed villains.

Can the Doctor and friends find the five keys and restore order to Marinus or will the evil Yartek get his hands on them? Can William Hartnell remember his lines? And just what is inside those wetsuits? Join us to find out...
