When I was 24 I went to Nigeria and it was such a culture shock, growing up in Australia and suddenly being the only white man in this unit full of black men.

Tender Mercies is a very low-budget film, but it was a huge budget compared to anything I had done in Australia. My fee for Tender Mercies was something like five times all of my Australian films combined.

Film is shot in fragments, and the same moments can be shot again and again until the director is satisfied.

With Cold Sassy Tree having its first production, I saw no necessity to do anything other than produce it with the correct setting.

I like to separate the music- and lyric-writing processes if I can. I'll sort of noodle around on my keyboard and my computer until I have a beat or a chord progression, I'll record it as a loop, export it to iTunes, then walk around with the loop and sort of talk to myself in the loop, and that's how I get the lyrics.

The act of writing surprises me all the time. A miraculous thing happens when you have an idea and you want to convert it into words... and then you start to create a work of art, and that's another miracle, and it remains mysterious to the writer, or to this writer anyway.

What I treasure most at any moment is intimacy, surprise, a sense of mystery, wit, depth and love. A handful of cherished friends offer me this, and the occasional singer or film-maker or artist. But my most reliable sources of electricity are Henry David Thoreau, Shakespeare, Melville and Emily Dickinson.

Until film is just as easily accessible as a pen or pencil, then it's not completely an art form. In painting, you can just pick up a piece of chalk, a stick, or whatever. In sculpture, you can get a rock. Writing, you just need a pencil and paper. Film has been a very elitist medium. It costs so much money.
