…revealed! That’s right, Kasterborites, in the run-up to next Friday’s Children in Need preview of the Christmas 2010 Doctor Who special, the title has been confirmed on the BBC’s Official site.

Rather than hopping over there to see the title, let’s play a gussing game to see if you can work out what the episode might be called.

I don’t think you’ll get it, personally, but you never know, even with these clues:

• So we’ve got time travel
• A man who is seen in an older body and a younger body
• It’s set at Christmas.

Hah! I bet that has got you stumped, hasn’t it? Got it? Oh. You have? You knew it was A Christmas Carol? How did you guess? I mean, like, just how?

Anyway, as we should all know by now, Friday’s Children in Need telethon will feature a preview of the episode which not only stars Matt Smith and Karen Gillan as the Doctor and Amy, but also Arthur Darvill as Rory (yey!), the great Sir Michael Gambon (Harry Potter‘s Dumbledore) as Kazran and the beautiful Katherine Jenkins (pictured). Don’t forget either unknown Danny Horn as the younger Kazran.

The Grand Moff says:

‘Oh, we’re going for broke with this one. It’s all your favourite Christmas movies at once, in an hour, with monsters. And the Doctor. And a honeymoon. And … oh, you’ll see. I’ve honestly never been so excited about writing anything!’
