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

You can act truthfully or you can lie. You can reveal things about yourself or you can hide. Therefore, the audience recognizes something about themselves or they don't -- You hope they don't leave the theatre thinking that was nice...now where's the cab?'

I'm a lot less serious than people think.

I have just returned from the dubbing studio where I spoke into a microphone as Severus Snape for absolutely the last time.

Snow Cake is a lovely film. Really proud of that. We shot it in 21 days. I thought Sigourney was amazing in it. And very, very accurate. I think there was some element that thought she had pushed it too far. But not at all when you do the amount of homework she had done and spent the amount of time she did with adult autistics. She was right on the money. And I think Marc Evans is a terrific director. He's a sweet, open, honest man and a really good director of actors.

If you could build a house on a trampoline, that would suit me fine.

A lot of the time I hate the theater. You think, 'I have to climb Mount Everest, again, tonight.' Oh, the theater is a scary place to be.
