I should say, a piece of advice that was given to me very early on by the principle of RADA (Royal Academy of Dramatic Art) which is where I went. When he auditioned me, he said, "Your speech, monologue, is fine. It's good. Yeah, I think you have ability but you're making it happen. Don't make it happen, let it happen." And that's a sort of subtle shift I think, as an actor.

I guess I'd love to be surprised by something I had never thought of.

Little moments can have a feeling and a texture that is very real.

So much of movie acting is in the lighting. And in loving your characters. I try to know them, and with that intimacy comes love. And now, I love Voldemort.

I think I feel more like you're an actor for hire and you take the jobs you want to take, obviously, and some pay well and some don't pay well at all but you go on a gut feeling and it's all a big adventure.

You dread that there will be real problems during filming.

The film depends on the audience's belief in this relationship.
