I'm very proud of the work I do, but I genuinely can't involve myself with an audience as early as somebody who's not part of the film can. So there's that side of theater that appeals to me, where you give something and the response to what you've created is a communion between you and the dark that contains however many people. It's thrilling not having a reflection other than through the people you're communicating with. But people ask, "What do you prefer?" and I don't have a preference. I love them both. I really do.

When you see a good horseman, you're unable to tell where the instruction is coming from. It's like telepathy.

I'm not loyal to one genre. I want to mix it up.

[Doctor Strange] is a really rich character. It's an easy thing to have a good old meal every day. It's great. Yeah, I'm excited.

[Doctor Strange] is difficult, he's arrogant, but he's kind of brilliant and charming and you'd think, "Yeah, I'd want him on my head if I needed brain surgery." He's good enough to warrant his arrogance and he respects other people but not when he thinks he's right and he'll just do what he deems needs to be done when he knows or feels that he's right and the problem from humility's point of view is that he is right, he's really really good at his job.

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.

I had a very sparse comic upbringing - not because I was being whipped into reading Chekhov and Dickens, but I read Asterix on holidays when I was a kid, and Tin Tin was featured, I remember, for a few years.
