I think what I loved in cinema - and what I mean by cinema is not just films, but proper, classical cinema - are the extraordinary moments that can occur on screen. At the same time, I do feel that cinema and theater feed each other. I feel like you can do close-up on stage and you can do something very bold and highly characterized - and, dare I say, theatrical - on camera. I think the cameras and the viewpoints shift depending on the intensity and integrity of your intention and focus on that.

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.

I've turned up to costume parties in the wrong costume. I've made social faux pas a plenty. I've put one foot in front of the other and fallen over.

If I'm playing someone who's smart, suddenly every character I've played is smart. If I'm playing a bad guy, every character is a bad guy. I suppose it's that thing where people want to see a through-line to understand you. I mean, you know, I have played pretty ordinary people too.

I genuinely don't know Julian Assange well. To authenticate an opinion, I really would have to meet him.

I drive a motorbike, so there is the whiff of the grim reaper round every corner, especially in London.

I was thrilled with how the first series of 'Sherlock' was received. It was such great fun to film, which makes it so rewarding when something you enjoy is so well received.
