I don't feel I'm playing villains all the time.

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.

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."

Kenya doesn't have much of an infrastructure for hosting a film.

I felt it [Shakespeare's Coriolanus] is sort of an examination of our dysfunction as a nationalistic, tribal entities. I think the world is rocking and cracking open in weird and worrying places. And I think Coriolanus, the play, reflected that.
