I occasionally go to the gym and I lift free weights, I don't use machines.

It's got to be a challenge but at the same time you have to feel as though you can play them - it's really dangerous to want to be a part of something just because you think it's going to be great. I've been sent plenty of scripts where I've known that it's going to be a great film and a successful one, but I just couldn't convince myself that I was the right person for the part. So, I think you have to be careful with that.

We live our lives by the water and if you don't know how to swim in Australia, it's like not knowing how to cross a road. It's an incredible survival thing that you really must learn when you're a child.

I've had frustrated storytelling juices that have been lying dormant for a long time, and I guess the documentary was a way of me telling a story that I felt most qualified to tell. And I loved it, and I'd love to do something else someday, probably more narrative-based. But I'm in no rush.

I've worked with some of the great cinematographers. So I'm always watching what they do and I'm watching how the director composes his shots, just because I find it interesting as an actor; you're trying to help them out as well.

I like the unknown. I like mystery.

The reason my kids come to the set is so I can actually see them.
