The Thirteenth Doctor

Peter Capaldi has announced that he is leaving his role as the Twelfth Doctor. He's been a fantastic Doctor and I'll be sad to see him go. What it does mean though is that at some point in the not too distant future the Thirteenth Doctor will be cast.

Lots of people are making lists of possible Doctors but many are not very likely. It's extremely unlikely that a major Hollywood actor is going to take the role. Even very big actors who have appeared in short series are unlikely to commit to a role as big as the Doctor. It's also very unlikely they will cast someone who has had a major Who role before- a guest part in one episode maybe, but not a returning actor like Alex Kingston or Maisie Williams. And I also think they are unlikely to choose an actor of a similar age-range to Peter Capaldi.

There's lots of talk that the new Doctor could be a woman. It's certainly a lot more likely now than it was when Peter Capaldi was cast. The Master's latest regeneration is a woman and we even saw a Time Lord regenerate from male to female in Hell Bent.

Whether the Thirteenth Doctor will be a woman is largely down to new showrunner Chris Chibnall. He is the man who will probably have the major say on the new Doctor. Personally I feel it would be ambitious for a new showrunner to come along and cast a woman as the Doctor- it's a change in the character dynamic which a new showrunner may not want to make straight away.

If they do choose a female Doctor Hayley Atwell would be my top tip. She's a great actor, demonstrated a fairly Doctor-ish role in Agent Carter and has no long-term commitments (it looks like her current TV series Conviction will not be renewed). Another highly possible one is Gemma Chan, who has become more successful in recent years and has played a Synth in sci-fi series Humans.

I do think it's quite likely that the next Doctor will be a different race. It's well known that a black actor turned down the role a few years ago (it's thought to have been Chiwetel Ejiofor by many). A lot of people seem to be talking about Richard Ayoade taking the role. As much as I like him it's hard to imagine him doing the serious drama parts of the role, and he's pretty busy in the near future hosting The Crystal Maze. There's talk of Game Of Thrones' Alexander Siddig taking the role but at 52 he is probably too old. My preferred non-white Doctor would be Sacha Dhawan- Doctor Who fans might know his for his role as Waris Hussein in An Adventure in Space and Time. He's a superb actor who I can really picture in the role.

The bookmaker's favourites for the role include Ben Whishaw and Rory Kinnear, both best known for their roles in the James Bond franchise. I like Kinnear but I fear he's a little old for the role and might Ben Whishaw be too big for the Doctor?

A likely BBC favourite would be James Norton. He shone in Happy Valley and War and Peace and seems to be an actor in favour with the beeb at the moment. He is busy for much of the year in ITV's Grantchester at the moment but he is certainly a possible.

I have a couple of lesser known ideas for the role. Bertie Carvel played Jonathan Strange in Jonathan Strange and Mr Norrell and I really feel would make a great Doctor. Then there's Damien Maloney, who played vampire Hal in two series of Being Human. He's a fantastic actor who I really feel ought to have a big role in something.

Could we maybe have someone Chris Chibnall has worked with before? I couldn't find many people in the Broadchurch cast list who I could imagine as the Doctor but one was James D'Arcy. He played Lee Ashworth in Broadchurch, a very non-Doctor-y role. But in Agent Carter he was the butler Edwin Jarvis who was closer to the Doctor- the variation in roles really shows how good an actor he is.

I also think there's a strong chance we'll get a fairly unknown actor. Hardly anyone knew who Matt Smith was when he was cast and the same could be said for the last three companions. It would be great if the show finds another amazing actor we'd never even heard of before.

I guess we'll just have to wait and see...
