Laughing and crying are really similar - what happens to your body. It's a very similar process in your diaphragm. Like a musician, you have to do your scales once in a while and warm up your voice.

New York City is crazy and beautiful and really close to my heart, and I've always had dear friends here - family, actually, I would say.

One of the first roles I had on stage was with a brilliant director in a brilliant play with a brilliant cast, but I just couldn't find my way into the heart of the character. I found myself straining a lot. When it started. I felt lost. That was the Eugène Ionesco play Rhinoceros. I don't think I was prepared for that. I don't think I had the full tool kit to do it justice. It's a very difficult play, it's an extraordinarily difficult part, and I never felt I really got it right. Far from it. To a degree, Hamlet was the same.

I've never been front and centre as an iconic American character [like in Doctor Strange]. Day to day, you know you're painting on a very big canvas.

I'm interested in art for all. I don't want it to be only the sons and daughters of Tory MPs who get to see my plays.

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

Talking about class terrifies me. There is no way of winning.
