The Weeping Angels. It's the concept (that they only move when you aren't looking at them). But there's one at the end of this season -- it's a new monster, and I'd say you have to wait and see that. That one is my favorite, so far.
One of the things we know about your character is her love of soufflé. Have you tried making one?
I had to be baking one in a scene recently. So I got the Google up and tried to figure out exactly how to do it, take it kind of really seriously to make sure I've got, like, the whisking right. But maybe that's what I should do over Christmas.
Is it odd returning to a "normal" world after living in The Doctor's?
"This" life is so exciting on a daily basis. Everything's so dramatic every day, and it's the end of the world every week. You're either running or there's a snow machine or rain machine, or you're in a harness and you're on wires. ... On an off day, I find that I get bored quickly, like, "Where's the Cybermen?"
The "Doctor Who Christmas Special" is something of a tradition -- do you have others you'll keep?
There are 13 of my family going to a cottage, so we'll be there watching. It's one of my grandmum's favorite shows, so it's big for her. But normally I get home from London and I haven't seen my family for a little while, and me and my mum always wrap the presents the night before with a glass of Bailey's. That's my favorite tradition at Christmastime.
What did your grandmother say when she learned you got this role?
I auditioned for Amy's best mate in it, and was pretty close to getting the part, and my grandma was absolutely devastated I didn't. So, we came back around, and I don't think she can believe it, actually. It is quite surreal for her, and she's quite looking forward to meeting Matt.
What do you anticipate that encounter being like?
My grandma's going to mess up his hair. She's going to be patting him and hugging him, and Matt's going to have really messy hair for the rest of the night.
