I've been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.

Mads [Mikkelsen] and I have a really epic brawl - a week shoot, lots of rehearsal - and he was just delightful. He's a dancer and a gymnast so he knows how to plant the moves. He was always saying, "Are you okay?" When you've got that level of mutual consideration you form a family very quickly.

I had a very sparse comic upbringing - not because I was being whipped into reading Chekhov and Dickens, but I read Asterix on holidays when I was a kid, and Tin Tin was featured, I remember, for a few years.

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.

When you start getting jobs, and see your mates from drama school, you don't really want to talk about it, because you have this innate sense of guilt that it's not fair that others aren't doing exactly what you're doing. I do have that.

I'm not loyal to one genre. I want to mix it up.

I can feel infinitely alive curled up on the sofa reading a book.
