OK so that’s not entirely true. The character of Dumbledore won’t be coming to DW, but rather the actor who currently plays him: Michael Gambon. Additionally it sounds like this will be the most Christmas-y DW special of them all:
“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. I was laughing madly as I typed along to Christmas songs in April. My neighbours loved it so much they all moved away and set up a website demanding my execution. But I’m fairly sure they did it ironically.”
The Christmas special will feature one very big guest star: Dumbledore. That’s right: Michael Gambon will be guest starring in the Christmas special. “Michael Gambon is as distinguished an actor as I can imagine and the fact that he was Dumbledore means that he is already known to millions of children,” Moffat said. Classical singer Katherine Jenkins will also appear.
BBC exec Ben Stephenson has revealed that the episode will be based upon Charles Dickens’ novel A Christmas Carol, providing a “clever twist” on the story, as well as giving “Amy and the Doctor for an unforgettable present!”
I’m quite pleased with Matt Smith’s take on The Doctor and while this season had a few episodes that were a little “meh”, the finale was pretty damned impressive. I’m also, oddly enough, a big fan of A Christmas Carol so seeing a DW take on the story is something to look forward to.
