I love perfumes. Every morning when my girlfriend and I come down to the courtyard in our block of flats we're assailed by the most delicious scent - jasmine round a doorway. It almost makes me swoon.

I am the character you are not supposed to like.

Parts win prizes, not actors.

One thing I will say - my job gets harder and harder. The more you understand about what you are capable of, the less the instrument can do it physically. It's an inverse equation, if that's the right phrase. I just slammed those two words together. It sounded right.

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

I can only see my limitations. That's just who I am.

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