I love the idea of playing something stupid or romantic. I'm not the smartest man in the room. I listen, and I learn, and I observe, but 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 been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.

Only when Stephen Strange has his accident and everything that he's ever had in his life falls apart that he becomes pretty monstrous. It's the self-loathing rage of a wounded animal and he doesn't have a coping mechanism at all. It ties in with the discipline and the magic of this world.

There's a heroic amount of effort that goes into making him [Doctor Strange] a superhero by the end of the film.

I actually do mind having a photo taken because it's one o'clock in the morning and I'm off my face.

I tell my wife all my secrets.

Having your adolescence at an all-male boarding school is just crap.
