If you take a child from South Africa and you put them in Boston, they're going to speak with a Boston accent. And so, that's a way to see the world as everybody is equal, not as a result of politics, but as human beings.

The problem when you edit a film together, when you shoot a film, you are drawn into the moment. You want each moment to be special and full of life.

It's part of my job to maintain the emotional reality and the naturalism even when the atmosphere is contrived.

If I have a good dream and I wake up happy. When I have an idea, I feel happy. Sometimes achievement and relationships can make me happy. I have a son and to see him grow - he's 22 now - that makes me happy.

I like to use a bit of chaos when I shoot. I think it may be something from the way I shot my first film - I was very scared, of course, and I prepared everything, I wanted to make sure that the characters did the right thing at the right time on the storyboard. But then I realised that in life, there is so much more than what you can predict or write in advance, that when you shoot the story, it's good to leave some gaps where you lose control. I think this combination of chaos and organisation gives a kind of quality.

I hate cynicism. I wipe it from me. I don't like cynical people. I don't like cynical movies. Cynicism is very easy. You don't have to justify it. You don't have to fight for it.

Sometimes, when people use too much blue screen in movies, the actors don't look credible, because they have their own opinion of what the thing will look like, and each person has a different opinion.
