'Tracks' is based on the book by Robyn Davidson who, in the mid-Seventies, decided to leave the city, go to the outback, learn to train camels and walk across the Australian desert to the ocean: a journey that is about two thousand miles and will take about six or seven months.

The spirit around leaving New York, for me, was that I just felt I needed to do something really outside of my comfort zone. And I really couldn't tell you at the time why I needed to do it. It wasn't like I was running from something dark; it was a desire to shake things up.

If you give me a typewriter and I'm having a good day, I can write a scene that will astonish its readers. That will perhaps make them laugh, perhaps make them cry - that will have some emotional clout to it. It doesn't cost much to do that.
