I'd sell my soul for a good cause.

I lived with a coffee farmer called Dukale on a trip I made with World Vision to Ethiopia, and realised there's no good reason for the disparity in opportunity around the world.

At the end of drama school, I made a contract with myself: I'd try acting for five years. I was 26. I had already spent eight years working in restaurants and gas stations. So I had seen enough small businesses to understand that that's what acting is: a small business.

I was probably more scared of my high school exams than I was of the Oscars. At the time you think it's everything and if you don't do well, your life's over. Opportunities are gone. So the more you do it, the less the fear is present.

I have two children and it's amazing how in tune they are with nature, with light, with smells, with time.

That's all about the natural order of things, the idea of nature protecting children but also children protecting nature.

Both my parents are English and came out to Australia in 1967. I was born the following year. My parents, and immigrants like them, were known as '£10 poms.' Back then, the Australian government was trying to get educated British people and Canadians - to be honest, educated white people - to come and live in Australia.

My parents were drawn to the idea that there was space and opportunity in Australia. For the meagre sum of £10, you could sail your entire family out to Australia, so that's what my father chose to do.

There was a whole display set up of all the X-Men paraphernalia. My wife couldn't resist telling this 5-year-old boy that I was Wolverine. The little kid looked up at me and he was staring at me.

I just love making a fool out of myself. I made my living as a clown at kids' parties for about three years.

I was brought up in a way that when you're at a dinner party, you don't grab a chip unless it's been offered to everyone else. It's the manners of being brought up by English parents.

There is anxiety, but it comes after you've finished filming because it's out of your hands; people are editing it, they're cutting it, marketing it. And it's... part your career sort of rides on that. But when you're actually filming it's a team thing and it really feels good there for me.

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.

My friends say, 'Man you're going to have kids sleeping on pillowcases with your face on it! You're going to be on toothbrushes and magnets and stuff.' I guess now that I'm a dad, I'm thrilled about that.

I had a fairly enlightened dad, though if you looked at his resume, it might not seem that way. He was a chartered accountant for Price Waterhouse. He was strict, and we had a very ordered life. To this day, I am the least materialistic person I know, because my father didn't raise me to just go out and buy this or that car.

You have to eat before you train. Otherwise, that really intense training, after about 40 minutes you start to flag.

I just find the evangelical church too, well, restrictive. But the School of Practical Philosophy is nonconfrontational. We believe there are many forms of Scripture. What is true is true and will never change, whether it's in the Bible or in Shakespeare. It's about oneness.

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'm a mad lover of sport. You cannot say a bad word to me about sports. So I know business is involved and I know it can be cynical, and, of course, I watch it, but for me it's pure.

As you get older you have more respect and empathy for your parents. Now I have a great relationship with both of them.

If you ask my wife, the biggest fault is my inability around the house. She says the only thing handy about me is that I'm close by. And, I have a terrible memory. I'm bad at saying no. I often double-book. There are a lot of things.

But anyone who's done a musical knows; whether you're dancing or not, physically it's the most difficult thing you can do.

Actually, I graduated from university as a journalist.

The last 10 years I have had to bulk up for roles and I'm naturally skinny, so I have eaten and killed so many chickens! I wouldn't even want to count. I need to balance that out.

I'm doing a new musical on Broadway, which opens in October called 'The Boy from Oz,' where I play Peter Allen. For those of you who don't know, he became first famous in America for marrying Liza Minelli.

I can look back on my life, where there have been moments where things might have gone the other way. Everything is like stepping stones, and I've seen people I admire falter. We're all vulnerable.

Breakfast is my specialty. I admit it's the easiest meal to cook, but I make everything with a twist, like lemon ricotta pancakes or bacon that's baked instead of fried.

I'm doing 'Les Miserables,' the movie. I've done a lot of musicals and a lot of movies, and I know there are not a lot of people in Hollywood who have been down those two paths so I've been like, 'Come on, let's do a movie/musical.'

Singing is incredibly physical.

As a boy, I'd always had an interest in theater. But the idea at my school was that drama and music were to round out the man. It wasn't what one did for a living. I got over that.

It's always interesting - how do you actually convey thought through song? We're used to the convention on stage. In film, we used to be used to it, and now sometimes it works and sometimes it doesn't. You need to be fresh and really look at the material.
