Doctor Who: 9 Great Third Doctor Stories

2. Inferno (Story 054, 1970)

http://www.youtube.com/watch?v=62j3wJpCR3k Astonishingly, Doctor Who hasn€™t played around much with alternate universes. They turn up all the time in shows like Star Trek, where by the Deep Space Nine era there€™s practically a super highway connecting the regular universe with the mirror universe. But in Who they€™re a rare and splendid thing. In this story, the Doctor finds himself in such a universe; one where the UK is basically a dictatorship and Liz and the Brigadier are rather more evil versions of themselves (you can tell because she has black hair and he€well, is clean shaven, though he does get an eyepatch and a scar). Soon the Doctor is stuck trying to save our universe while being keenly aware that he probably can€™t save the other one, creating a truly great moment of ethical concern for the character. It is a bit silly when you have an enemy that can be beaten with fire extinguishers, but that one complaint aside, this is a hell of a great story.
