[on BBC's Sherlock] It's a rare challenge, both for the audience and an actor, to take part in something with this level of intelligence and wit. You have to really enjoy it. It's a form of mental and physical gymnastics.

[Doctor Strange ] is slightly more specialised than Spider-Man or Superman or Batman, but he's very loved by people who know him.

I think it's fair to say that, yeah, I'm playing Doctor Strange, I get there.

That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think. When I walk through that door, it's about home. If I didn't do that, I'd become consumed by one thing only and damage the people who love me. And it would damage the work.

I had a real yearning to make use of the opportunities I had at school. When I heard about the gap year of teaching English at a Tibetan monastery, I knew I had to do something about it really quickly, otherwise it was going to get allocated.

All the backstories are there but not talked about.

You let things run in order to have some sanity and be able to do your work and not feel pre-judged.
