I don't plan a career. That doesn't work for me. I just have to go with my gut.

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.

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.

You have to just dive over the edge. You haven't got time to mess about.

The tensions between authority and the people need to be heard, especially when they are suffering and they can't eat.

I never studied anything about film technique in school. Eventually, I realized that cinema and theater are not so different: from the gut to the heart to the head of a character is the same journey for both.

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.
