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.

I've always enjoyed doing a huge variety of roles, which I think helps, instead of settling for the things I might be most comfortable with.

I think fear is a very healthy motivator.

I've often had the fortune to work on projects with a small theme I find very interesting enough to pursue and to be passionate about in the context of the story, then it may turn out there's a universality about my character which still resonates with many people as well.

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 believe people instinctively know that about writing, yet people get confused about that when it comes to acting.

Once you click into a character, to a certain degree, you can do a lot else. You can do other stuff, then come back and click right into the character. It's sort of funny that way, the way the mind works. Once it's there, it's sort of there. For the stage, for example, all through the day, you're not onstage. You're living your life, la-la-la, then the lights go down, then boom! All of a sudden, you're in this thing. There's a kind of reflex muscle trigger that happens, and all of a sudden you're back into the role. It's just getting there in the first place that's tricky.
