Being an actor means asking people to look at you. I guess I accept that. But it's a profession in which the job is to show another world and other people. You may access it through bits of yourself, and your imagination and experience, but actually, in the end, you're not playing yourself.

Voldemort? That might be real.

He's really sort of the devil. He's completely emotionally detached. He has no empathy. You find that in psychopaths. It's about power with Voldemort. It's an aphrodisiac for him. Power makes him feel alive.

There's a challenge to playing these fantasy figures because they are fantasy figures. You have to enter into this sort of imaginative world of the writer.

When you get into the edit you'll understand what making a film is. You'll see all the things you missed and all the possibilities you have from what you shot.

I don't feel particularly comfortable about actors using whatever power they may have to push their beliefs, unless they're extremely well informed.

When I first filmed things, they were always slightly awkward.
