Success.. is all about being able to extend love to people... not in a big, capital letter sense but in the everyday. Little by little, task by task, gesture by gesture, word by word.

Performance is made in the editing room, and I've come to see the truth in that - the idea that they say performances are usually made in the editing room because what you film is the raw material. I think just going through the process of saying, "Which take do we use? Why is that the take we want? I want that take can you edit again, I'm not sure that's the one, I think it's this one." And just because you go through that process, I think somehow it's made me sort of more open about the [actor's] possibilities.

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'm interested in the spirits of people. In the theatre, there's the acting part of acting - and I'm not saying that can't be great - and there's the essence. To explore that essence, you need a key, a look, a gesture, an insight that unlocks the person's soul.

God is not anything human. God is a force, God is chaos, God is unknown. God is terror and enlightenment at the same time.

It [the scene] can be something given to you and you go, "Ah this is a good idea, I can work with this." Sometimes it cuts right across your instinct and that's when I might resist. Even if the director might be insistent, I think it's very important to say, "Look, I'm not feeling this. I'll try to make it work but I got to let you know."

The actor shouldn't edit themselves or be anxious. And the actors that I admire are always the ones who are inventive and their imaginative life in free-willing. It's a director's job to go, "No here, don't do that, go there."
