I love working in New York theater.

The directors you trust the most are the ones, when you ask them a question, they've got the guts to say, 'I don't know.'

So you can't judge the character you're playing ever.

Acting touches nerves you have absolutely no control over.

Every so often you read a play and a character just speaks to you - almost seems to speak through you, in fact.

I knew with Snape I was working as a double agent, as it turns out, and a very good one at that.

On the screen were some flashback shots of Daniel, Emma and Rupert from ten years ago. They were 12. I have also recently returned from New York, and while I was there, I saw Daniel singing and dancing (brilliantly) on Broadway. A lifetime seems to have passed in minutes.
