So recent TV news states that Matt Smith, is hanging up his sonic screwdriver and Tardis key, at the end of the current series. This is one of the most ambivalent regeneration a in my mind, because while I like Matt Smith as an actor, much of his run has been pretty crappy. Besides the worst companion to date in River Song (Seriously! worse than like 10 Adrics!), the show just seemed to put too much schmaltz in the doctor /companion relationship. As well as the almot godlike way they seemed to try to turn the doctor into a bit more of a Mary Sue in his own right. Even the set up in Tennant's last episode of the Doctor turned into an exercise in teary eyed nostalgia, and of course ditching the whole of Galifrey annoyed me almost as much as the trying to make the master a much more sympathetic character. but enough about that Matt Smith will be the Doctor no more after the Doctor Who christmas special.
So now comes the big part who will play the new doctor? Of course theories are flying even this early. John Hurt is probably one of the biggest names, and of course the ever popular speculation of the doctor swapping genders. Stephan Moffat had actually done this in the Comic Relief parody of Doctor Who, Doctor Who, and the Curse of the Fatal Death, and he caught quite a bit of hell for it. So we shall see.
