I think there's nothing more amazing than helping people every day.

I cry at random things, like a flower, or someone giving me a present, or my sister giving me a nice hug.

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.

Only do acting, if you don't want to do anything else. And know that it's a tough journey with a lot of rejection along the way. You have to have a lot of self-belief.

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 just feel incredibly lucky. I went to drama school and about 28 of us graduated. I graduated from drama school in 2000, and I would say about two of us are working and able to make a living out of it. It is a tough profession. To have the kind of success I have had is really amazing, and I am incredibly grateful.

I really like Roland Moret, Alexander McQueen and Marios Schwab, a young British designer.
