Back when we watched “Planet of Evil,” I wrote about the Radio Times 20th Anniversary Special. When my mate Blake got hold of a copy, I asked him “What do you mean there are only five Doctors? I’m telling you there are at least a dozen!” And according to “The Brain of Morbius,” there are. Philip Hinchcliffe and Robert Holmes decided to do a big, weird, wonderful retcon and introduce eight Doctors prior to the one we’d previously called the first.
The situation is that the Doctor and Morbius are having a mind-bending challenge, and the faces of the three previous actors to play the Doctor pop up in the space between them while Morbius taunts “Back, back to your beginnings! How long have you lived?” So we see Pertwee, Troughton, and Hartnell again, followed by eight members of the production team and some BBC directors, including, cheekily, Hinchcliffe and Holmes themselves. They played the fourth and seventh Doctors.
I think that when I first saw this, I just took it as new information, not that I was actually counting faces, just learning that there was this thing called regeneration. I didn’t question the number.
It didn’t take, but the show didn’t actually formally retcon this retcon for another seven years. So while we all know and love Tom Baker as “The Fourth Doctor”™, as far as 1976 goes, the production team was actually thinking of him as the Twelfth! Nothing onscreen actually contradicts this until “Mawdryn Undead” in 1983, which returns things to normality and flatly states that Peter Davison’s Doctor is the fifth one. And then the same story goes and screws up the UNIT chronology.
But one thing the show’s never actually told us – and why should it bother? – is whose faces are they, if not the Doctor’s? I asked our son “Who were those eight other faces?” and he immediately replied “Morbius’s faces!” as though I had not been paying attention. That’s one of a few fan explanations. I figure that if it’s an explanation a six year-old can provide and get behind, then it’s probably the best answer!
