Having gone through editing process, I can see that in actor's faces there's point where they're not managing their performance and that's, I think, the best place to be. You've done the homework, you've learned the lines, at that point you just sort of let it out.

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's not great if someone gives you sort of bland praise without giving you clear direction and say, "This is good, let's try it like this." I have worked with someone who seemed quite inarticulate and just would say, "That's good, that's good." That's very frustrating because - it's nice to know something is good but you know it can always change.

It's great to be on a set where there's time and there's focus and there's also a kind of adrenaline thrill on a set where people are saying: "We have to get this shot, we've have to go, we've got to move on!"

There is a tension in relationships between wanting to return to the womb, but also wanting to be free. Because sometimes the woman's attentions can be overly maternal, and you want to go, 'Ahhhh!'

Kenya doesn't have much of an infrastructure for hosting a film of this scale. Our producer decided that for the film to really work it had to be in Kenya.
