I've heard lots of rumours, none of which I'm allowed to tell you anything about. I'm privy to them actually, yes, I have got a copy of the script which has got my name embossed across it, so it's top secret, but there's other stuff, lots of other things that are going on that people should keep their eye open for around the 50th Anniversary Special!

I love the BFI. I love the Doctor and hope you enjoy this presentation. Joe Ahearne directed five of the 13 episodes of the first series. He understood the tone the show needed completely – strong, bold, pacy visuals coupled with wit, warmth and a twinkle in the performances, missus.

If Joe agrees to direct the 100th anniversary special, I will bring my sonic and a stair-lift and – providing the Daleks don’t bring theirs – I, the ninth Doctor, vow to save the universe and all you apes in it.

I absolutely loved what David Tennant was doing on Doctor Who. There was such a quizzical nature to his character, a sense of whimsy, but he could still get very powerful emotion out of the character — a lot of intensity, a lot of anger — just an incredible display of range.

Well that was all a bit Keystone Cops, wasn't it? Our biggest surprise, our most secret episode, a revelation about the Doctor that changes everything ...

... and we'd have got away with it too, if we hadn't accidentally sent Blu-ray copies of Name Of The Doctor to 210 Doctor Who fans in America. Security-wise, that's not GOOD, is it? I mean, it's not top-notch; it's hard to defend as professional-level, hard-line secrecy.

My favorite fact is that they're Blu-Rays. Listen, we don't just leak any old rubbish, we leak in high-def – 1080p or nothing, that's us. Every last pixel in beautifully rendered detail. It's like getting caught extra naked.

But here's the thing. Never mind us blundering fools, check out the fans. Two hundred and ten of them, with the top-secret episode within their grasp – and because we asked nicely, they didn't breathe a word. Not one. Even Doctor Who websites have been closing their comments sections, just in case anyone blurts. I'm gobsmacked. I'm impressed. Actually, I'm humbled. And we are all very grateful.

Now you might be thinking, what does all this matter? It's a plot development in the mad old fantasy world of Doctor Who, why is that important? Well of course, it's not important, and in the scheme of things, it doesn't matter at all. Just as it doesn't matter when you're telling a joke, and some idiot shouts out the punchline before you finish. It's irritating, that's all. It's bad manners.

Well, no bad manners here! Two hundred and ten Doctor Who fans kept the secret, and many, many more fans helped. I wish I could send you all flowers, but I don't know where you live (and, given our record, you really shouldn't be sharing private information with us). So instead, there is a little video treat.

Ten plus 11 gives you ...

BBC AMERICA celebrates the third Doctor, Jon Pertwee, in a new special of Doctor Who: The Doctors Revisited.

The Doctor is forced to race against time, in order to stop humanity from being replaced by a generation of terrifying plastic replicas.
