We are now living in a jungle where the strong eats the weak,we are not better than the Arabs to despise them.

I'm more relaxed about how the editing process will create a performance and that, in a way, gives me a sense of freedom.

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.

Like anything to do with trust, in any relationship it emerges and just the chemistry, vibe between two people an actor and a director. You just know whether this is someone I like to be with whose interaction with me I believe in.

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.

I have a great editor and I enjoy, in a masochistic way, being ruthless about my own performance. How do I know, but I think I'm quite good at saying, "That's no good. That's no good. That's it. That's it. That's good." And I'm with the editor who goes, "No, I think you're wrong. That's not your best." There's an initial point in the editing, if you're directing yourself, especially in my case, where you go, "Ouch, ouch, ouch, I can't watch this." And then, there's a point where you become hard-nosed and just take your neurosis away and go, "What's working? That's okay. That's okay. We can lose that, and lose that." You get objective about it.

News reports can overwhelm us. We can be appalled, we can sympathise. But what is hard to grasp is the sense that, at this moment, people are working, organising - not just at an executive level, but on the floor, in the warehouse. A man is packing a box of oral rehydration tablets; maternity kits are being prepared; education kits are being packed. And somewhere, tomorrow, those boxes will be unpacked and a child with life-threatening diarrhoea will be saved, a baby will be born in more hygienic circumstances, a girl will receive her first exercise book and her first pencil.
