I've gone up two suit sizes. The character I'm playing, he's strong, I can say that much. I've changed my physique a bit, so that requires eating like a foie gras goose, well beyond your appetite. Providing I don't feel too ill, I then work out two hours a day with a phenomenal trainer. It's the L.A. way.

[Sherlock Holmes] has to understand the world. That's very much John's [Watson] influence on him. But like a lot of the friendships and relationships in that world, it's born out of necessity. It makes him better. There's a pragmatism to it. It's not whimsical or sentimental. It's born out of necessity.

That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think.

I'll always do 'Sherlock' - it's something I'm not going to give up on.

Live a life less ordinary.

Pull the hair on my head the wrong way, and I would be on my knees begging for mercy. I have very sensitive follicles.

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