I feel so lucky to have both a son and a daughter, because there's a different relationship with each of them.

To make films like 'X-Men' work commercially - and also have some class - is one of the hardest things there is to do. I want to be seen to be able to cross lots of genres and still be 'fair dinkum,' as we say in Australia, which means genuine and true and, well, unique.

I'd sell my soul for a good cause.

I once sang 'Summer Nights,' from 'Grease,' at a bar in Melbourne with John Travolta, who's a good friend of mine. He looked cool singing the part of Danny - sitting in an armchair, smoking a cigar - while I got stuck playing Sandy.

I do heavy weights in the morning for about an hour, and then I do 45 minutes of higher-volume lifting in the afternoon. My least favorite is the legs... I do quite a few chin-ups and rows. I do mostly old-school lifting with a lot of squats.

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.

Meditation is all about the pursuit of nothingness. It's like the ultimate rest. It's better than the best sleep you've ever had. It's a quieting of the mind. It sharpens everything, especially your appreciation of your surroundings. It keeps life fresh.
