When are you ever settled enough to have kids?

One of the fears of having too much work is not having time to observe. And once you get recognised, there is nowhere for you to look any more. You can't sit on a night bus and watch it all happen.

Talking about class terrifies me. There is no way of winning.

I feel that TV and film feed off each other well. It's more in the perception of the viewer than it is of the actor.

We have a lot more unlikely heroes now. It’s not just the guy with guns—it’s the guy with brains.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

I am very flattered. I have also become a verb as in "I have cumberbatched the UK audience" apparently. Who knows, by the end of the year I might become a swear word too! It's crazy and fun and very flattering.
