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.

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.

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.

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.

But in another world, another life, probably growing up in another country, I might have been more of a dancer.

I'm quite an independent person, and I had to be. As a boy and growing into a young man I had to look out for myself. And now I'm very family-oriented. It's a big priority in my life.

When you dance, your body just wants to find its natural weight. I'm naturally a lot more Tommy Tune than I am Wolverine.
