When I go to a movie, I'm always thrilled if I've seen an actor do something and I didn't realize until the end of the movie that that was that person. I love that.

Ultimately the most challenging thing, always, is to just be convincing

To work in America or other places is more about curiosity, because I'm dealing with cultures and sensibilities that I don't really know. So I'm having to sort of investigate them, which I'm fascinated in, but it comes from a place of curiosity rather than a real need to get something out of my system.

It's really interesting making films and actually seeing the life that they have in the subsequent years and seeing which ones stand up over time and which ones sort of fade away.

Most of the time when I'm in Australia I'm not really working, it seems. I'm just at home, getting on with renovating my house or writing music or whatever. So I get back to doing all the stuff that I naturally do. Whereas if I'm away working, that's all there is to do, is to concentrate on the work.

The first thing I need to get sorted out before I can then move forward, before I can feel any confidence whatsoever, is the voice.

I suffer from overheating quite easily.
