I'm sort of focused on my long-term goal of carving out a career that's for life, rather than being a flash in the pan.

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 ate healthily, but there was no snacking, no drinking, no bread, no sugar, no smoking. Afterwards I had a pork belly roast.

'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.

Doctor Strange is selfish but he's still saving lives.

I've never been front and centre as an iconic American character [like in Doctor Strange]. Day to day, you know you're painting on a very big canvas.

[While voicing cartoons] you have to lose your sanity and inhibitions and any kind of dignity and just throw yourself around a bit.
