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.

Doctors and nurses do crazy hours and keep an ideal afloat through the love and care that they have for their craft and their patients and the institution of the NHS. We should be very proud of it.

I'm not one for doing the children's party version: "Hi, I'm a character in a movie and now I'm in reality!" I was doing the last shot of the film before reshoots outside their shop. I was starting my run into the frame and I thought, "You are literally ending where this began. The loop of serendipity's too much to not go in and acknowledge it." I just wanted to see the look on their faces.

I was never geeky about anything.

[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.

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

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.
