I became an actor by doing school plays and youth theaters, and then National Youth Theatre of Great Britain. And then I did study at the London Academy of Music and Dramatic Arts. For me that was a good way to enter the field, to work in the theater.

David Mamet was great to work with. He was everything that I thought he would be as a director. He's incredibly articulate, an easy collaborator. Extraordinarily knowledgeable about film and writing.

Ive always liked the idea of being a father. And Ive always romanticised it, because I lost my father when I was young. In a way, all of the complications that come with my career are about that.

I remember being very affected by what was going on there towards the end of Apartheid. And the subject is still very pertinent, politically, to what's happening around the world today, in terms of negotiating peace talks. I had always been interested in this period of change in South Africa, generally, for a variety of reasons.

I wanted to be an actor ever since I got on stage for the first time, aged 13. Before that, I thought I might follow in the medical footsteps of my parents: my father was a doctor, my mother a pharmacist.

The only way to be an actor is to find ways to work as an actor, even if that means doing a one-man show by a river.

I think the crucial thing about being an actor is to be doing it.
