I am a fan of a bright sock. They're bold.

The fact that you've got zombies in this movie allows you to make slightly bolder choices tonally.

I just love vampires.

As an actor, you'll have ten parts in 2015 - eight of them will go to the other actors above you and two of them you might be close to, and you try to make them as good as you can.

I would be sitting in my flat watching TV, and 'Doctor Who' would be on with my flatmate there. I would have loved to share the fact that I was the new Doctor, but I couldn't. I was going mad. My dad was rather flabbergasted. When I told him, he laughed. He was excited, elated and very proud.

As an actor I can sort of smell a duff note, that isn't full of that much conviction. My worst thing with directors is when I know more than them about the character.

It's very rare that I play cool people. I'm not sure what that says about me.
