Speaking of the Christmas episode she said:
“We’ve finished the Christmas special so that’s all in the can and it’s a good one. It’s really funny but it’s also heartbreaking and you get a glimpse into Amy and Rory’s honeymoon, which is an interesting one.
“There’s a really, really scary monster in the Christmas special.”
And when probed on whether she will be on the show beyond series 6, she added:
“Who knows? I’m just taking it series by series and I’m just having fun. So, I don’t know. I have no idea.”
