Matt Smith has told DigitalSpy that fans won’t be left disappointed by this year’s Christmas special, which recently finished filming in Cardiff.

He told the website: “I think it’s going to be brilliant. The Doctor meets this old Christmas miser, played by Michael Gambon. He was just brilliant. Perfect for Doctor Who. What a Doctor he’d have made in his day! I always wanted to do a Christmas episode. It’s a real milestone, so I’m very pleased to have got one in the can.”

In the interview, the actor also discusses last month’s Doctor Who Proms, which he describes as one of the “seminal moments” of his career. “It’s not like when you’re doing a play and it’s press night and you think ‘Oh God, what on Earth are they going to write?’,” he explained. ”The audience just wants you to be cool and Doctor-y. I loved it.”
