I'm always keen to use my body in my work, so I'm looking forward to the motion capture for Smaug. Both Gollum and King Kong were primates, whereas I'm playing a serpent, so it'll be interesting - I'll have to tie my legs together, possibly, or else they'll be kind of splayed out to the side as a reptile's should be.

You'd have to be pretty hard-nosed not to feel some sympathy for the guy [Doctor Strange].

'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.

Mystique is rare now, isn't it? There aren't that many enigmas in this modern world.

I've been broody since I was 12, but I can't just get anyone pregnant. It has got to be the right person.

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

I don't wear a mask, I don't have a suit. It's not some CG double or a stunt double. The suffering the character [Doctor Strange ] goes through is immense!
