There's always a theme I'm drawn to, that we humans are not good or bad. We're all a mixture of both. We can have great compassion or commit great violence.

Most big popcorn movies are 'bad guy does something to good guy, good guy gets revenge on bad guy, sets the world right, and moves on.' And 'Ender's Game' is just not that simple, so it's an exciting challenge. It's a little terrifying, and let's see how audiences respond.

When we watch stories, we learn empathy, we learn compassion, and hopefully we achieve some sort of understanding.

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.'

The reality is that art has often risen to greater heights than the people who created it. Many flawed artists have created great works of art. You have to decide if you are going to listen to Richard Wagner's music or not because he was very anti-Semitic.

I'm drawn to bad romances.
