There are other people who don't mind shouting from the pulpit and being judged for it, and they do a hell of a lot of good - real, on-the-ground, life-changing good. So I think it can sometimes be a balancing act.

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.

Cumberbatch - it sounds like a fart in a bath, doesn't it? What a fluffy old name. I can never say it on a Monday morning. When I became an actor, Mum wasn't keen on me keeping it.

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

Even though Doctor Strange is an established character, when you're doing an origin story there's a lot of room for manoeuvre.

People's hands fascinate me. It's tempting to look at a businessman's left hand and see if there's an indentation from a missing wedding ring. Or maybe there's a tan line and the skin is pressed down where's he's worked a ring off his finger.

I just increasingly enjoy the quiet moments when I can be on my own with my friends and family, or with a book, having a live experience. That's really what I crave, and I always have done.
