It's absolutely physically demanding to play the role of Wolverine. There's a lot of action, and I try to do as much of it as I can because it's better for the audience.

There is still boxing, but there's just no money in it anymore. If you went around the world and asked a bunch of people under 20 years old, to name a boxer, I bet they couldn't name one. They'd be able to name a UFC fighter though. When I was younger there was Mike Tyson and we watched everything. I'm not saying its gone, or its going to go, and it could easily be ignited by another fighter, but it's just that idea that UFC is more violent, that desire for more spectacle, has captured people's attention.

My favorite play in drama school was 'The Bacchae.' It's about a king who literally gets eaten alive by all the women in the play in a kind of orgy - it's related to the word 'bacchanal' - and I loved that idea of animalistic chaos and following our own desires.

One afternoon when I was 9, my dad told me I'd be skipping school the next day. Then we drove 12 hours from Melbourne to Sydney for the Centenary Test, a once-in-a-lifetime commemorative cricket match. It was great fun - especially for a kid who was a massive sports fan.

My father taught me that losing your temper is a self-indulgent act.

Luckily, I'm not afraid to make a fool of myself.

The most scared I'd ever been was the first time I sang at a rugby match, Australia versus New Zealand, in front of one hundred thousand people. I had a panic attack the night before because people have been booed off and never worked again... just singing one song, the national anthem.
