Well, since we don’t have as many former incarnations of the Doctor as we might have wanted in DOCTOR WHO’s 50th anniversary story, fans need to argue toll obsess over something — and that something is the mysterious character played by science-fiction vet John Hurt.
Word got around that he was playing a “forgotten” Doctor who was lost in the Time War and fits between the Eighth and Ninth Doctors, or even an alternate version of the Ninth — bumping forward the number of incarnations and pushing the existing 11th Doctor into becoming the 12th.
Hurt finally got around to (sort of) addressing the issue, but the quote attributed to him didn’t seem to help: Hurt said he plays “part of the Doctor” in a “kind of trinity” involving David Tennant’s 10th Doctor. This was apparently taken as “proof” that he’s playing a new Doctor.
I don’t buy it. Him saying “part of the Doctor” makes me think of the Valeyard from the “Trial of a Time Lord” season. Recall that the Valeyard was supposed to be some kind of distillation of the Doctor’s bad or sinister parts somewhere between his 12th and 13th incarnations. (At least, that was according to the Master). Well, why can’t Hurt be playing the opposite type of being — the Doctor’s concentrated good? The AntiValeyard, if you will. The Dream Lord from “Amy’s Choice” was also a personification of the dark side of the Doctor. So let’s see his good qualities, as well.
