I go to the theater two or three times a week when I'm in London. Whereas I feel guilty going to the cinema in the middle of the afternoon.

On so many levels, acting in film and TV is so much the sum of its parts, and somewhere in there, there's an alchemical thing that makes something happen or not - that makes something connect or not. Now, of course you want to make work that people see, but the enjoyment I get out of acting is playing characters.

I feel like J.K. Rowling's world is one that is owned by everyone in some ways. People have grown up with it and have such a sense of that universe that there's something kind of wonderful seeing everyone get involved.

Ladies and babies, and mortgages, for that matter, can all wait. Acting has done a strange thing to me, though. I often sit there, thinking, 'I love this, but I wouldn't put my daughter on the stage.'

I draw and play the piano badly. But when I’m doing those things, I’m concentrating so hard there’s no room for worry. I find that onstage, too.

Everything about filmmaking is incredibly weird, and there's nothing natural about watching yourself on the big screen or hearing your voice. It's that same thing that you feel when you watch yourself on a video camera and you hate the sound of your voice - it's that times 800.

Tequila is my salmon.
