I think anyone who works in medicine has superpowers.

I always seem to be cast as slightly wan, ethereal, troubled intellectuals or physically ambivalent bad lovers. But I'm here to tell you I'm quite the opposite in real life. In fact I'm a f**king fantastic lover.

'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.

The guy [Doctor Strange], he's like most of us, he's uncorrupted flesh from the beginning of his life, he's somebody who's not marked with original sin or any kind of crap like that. He's somebody who's come into this world and had experiences that have shaped him to the point that we first meet him. There's always got to be leverage. I think there is some clear explanation of that within this film, but potentially further down the line...for more of that to come out as well.

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.

The awful lesson of history is that we too often ignore people, just because they're foreigners or different from us.

Landing the role of Stephen Hawking was the most positively surprising thing that has happened to me.
