It's one of the things that attracted me to the role [Doctor Strange] is the fact that it's a really widely origin story, I mean this is part of it, but of course there's the whole chapter before where he's the neurosurgeon who has the accident. It's fantastic.

'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.

There's a huge raft of roles that actors in our culture perform, and you can see any one of about three Hamlets in a year. It's not something to be completely daunted by.

I'm always playing characters with intellects profoundly superior to mine. That's great fun, even though it's as much a fantasy for me as for the people watching me.

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.

One of the first roles I had on stage was with a brilliant director in a brilliant play with a brilliant cast, but I just couldn't find my way into the heart of the character. I found myself straining a lot. When it started. I felt lost. That was the Eugène Ionesco play Rhinoceros. I don't think I was prepared for that. I don't think I had the full tool kit to do it justice. It's a very difficult play, it's an extraordinarily difficult part, and I never felt I really got it right. Far from it. To a degree, Hamlet was the same.

I like to think that we’re revolving on this planet and revolving through the galaxy. I love having context that’s so much bigger than I can fathom. It’s fantastic to realise how insignificant you are.
