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.

Sometimes when you do fight scenes you think, "Oh, I'll be hit in the face," because people get carried away with their vanity and want to look too cool to care, but we were all really careful with each other.

It's an interesting arc. You start with a character [Doctor Strange] who's likeable and charming but very arrogant and distant. He's funny but you can see there are massive holes in his life. It's a very painful transition and all that he becomes is tested so quickly and violently.

The further you get away from yourself, the more challenging it is. Not to be in your comfort zone is great fun.

I'm a Prince of Wales Trust ambassador, so I'm all about giving youth an education, a voice and a chance to not take the wrong road.

I really cannot get over the generosity of our Tibetian teacher. He said, "Don't punish yourself. You're going to be a student at a university in the north of England. You need to have your experiences and have your fun, and not judge yourself. Don't live in guilt and regret."

I always get self-conscious about what I look like in a film, but less so if I'm a character very far removed from who I am. Then I just worry about the performance, and that's equally an odd experience.
