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 never talk about 'Harry Potter' because I think that would rob children of something that's private to them. I think too many things get explained, so I hate talking about it.

I do feel more myself in America. I can regress there, and they have roller-coaster parks.

I always feel that when I come to Edinburgh, in many ways I am coming home.

I'm still living the life where you get home and open the fridge and there's half a pot of yogurt and a half a can of flat Coca-Cola.

Give me a window and I'll stare out it.

Actors are agents of change. A film, a piece of theater, a piece of music, or a book can make a difference. It can change the world.
