When you film in Africa, it's almost like a character in and of itself because it is so beautiful and has this special magic that I've never experienced anywhere else. There is something so incredibly beautiful about the light.

I am always interested in affecting people in some way, making them think about particular areas of history that they have never thought about or that they may have thought about in one way and then changing their view.

You don't want to just preach to people; you want to get them emotionally involved, and I think you do that with a wonderful human story about one person's struggle.

To have the kind of success I have had is really amazing, and I am incredibly grateful.

What I generally get from being in Africa is a sense of warmth and openness. As a stranger, you are always welcomed into people's homes and people are always offering you food. That generosity is incredibly touching.

Education opens the door to everything in terms of having a career and an impact on society and not being a slave to your job, really.

I did not enjoy Cambridge. But I shouldn't blame Cambridge alone. I wasn't ready for university or for the wrench of leaving home. It was a big cultural shock.
