Athol Fugard became famous as a playwright, so although 'Tsotsi' the book was written in the '60s, it was only published in the '80s. It was then optioned pretty much every year by producers. I think the problem was that holding onto its period setting made it very hard to get finance.

In the early '90s, I was hired to write educational dramas about HIV and AIDS in the shantytowns. I did that for two and a half years, and then I was hired on other films. When 'Tsotsi' presented itself, I thought, 'This is not a world I grew up in, but I've spent a great deal of time writing about it and researching it in my past.'

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
