He is Ho ho ho!, if I can say that.
I wanted to do him slightly differently.
I think that Ho ho ho!
Hes a bit like De Niro inMean Streets.
Hes funny, hes kind of flirty and charming with Clara.
And we never know why.
Its never remarked upon but from the get-go, theyre kind of at each others throats.

Which is great, cos you think, Why did this happen?
Where did this come from?
Its like Maggie Simpson and that baby with one eyebrow, which is kind of funny.
A lot of the crew are wondering why there is just that beef?
And Im hoping thats interesting enough that Steven might bring me back again next Christmas!
Hes just really tired of them.
And theyre back-chatting him all the time.
And within earshot too.
I think hes really tried of them but hes very protective towards them.
Hes their boss essentially.
Ive enjoyed working with those two [Nathan McMullen and Dan Starkey].
Theres lots of improvisations in terms of things we whisper and physical ticks.
Its nice to work that in and have the freedom to be able to do that.
We shot a scene yesterday on top of Claras house.
Bear in mind it took them about six weeks to build the set for a days shoot.
Its absolutely amazing and it looked amazing.
Nick addressed the topic of the scary monsters in the special, the Dream Crabs:
Christ yeah.
Anything that clings to your face and potentially kills you is really creepy!
I managed to turn him into a giggler, he laughed a lot.
I never imagined him to be a giggler.
I managed to get him every day, which was great.
But then he sees me dressed as Father Christmas.
[Laughs] I think its tougher for Peter.
As an actor you wanna work with great actors, you just up your game.
I still have that weird fanboy thing when I see him and I think, Theres Doctor Who!
I moved away when I was eighteen and it drifted away from me.
And I loved Matt Smith, I loved him as the Doctor.
And then the baton changed from him to Peter its been fantastic.
I love what hes doing.
It makes Saturday nights special.
