I try to be upbeat. I read this book which tells you to write down everything that you're grateful for each day. Now I'm constantly noticing all the little things that make me joyful.

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.

It is great to be a part of big-budget movies, but it is harder to feel like you are contributing, in the sense that it has such big machinery behind it.

I started acting when I was seven. And I went to a local drama school which is very well-known in London. Because of that, I started getting jobs, and I worked all the time as a child, pretty much non-stop.

Without education, you really can't dream as a child.

One of the saddest aspects for me about filming in South Africa was that the real inequalities are still very much in place - and those are economic inequalities.

When I have finished a job, done all the promotion, and it's been received well. Then I can allow myself the luxury of a break, and chilling out with my family and friends, and taking a nice break knowing I've done a good job.
