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.

I love Sam Mendes. He's a fantastic director.

I've never been that person who wants a Rolls Royce or wants to live in a mansion or what have you.

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.

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.

I never make suggestions. I really don't. I know a lot of actors who get a part and then they dissect it and they want to change it and they want to add stuff. I'm always amazed and so impressed by actors who do that.

At Cambridge, it was the weirdest culture. Everyone pretended they didn't do any work, yet it was so competitive.
