It's fair to say that, by 'X-Men 3,' Wolverine had gone a little soft, and I agree with them there. What fans love about Wolverine is his more uncompromising approach to life. He is who he is. He's not always a nice guy. He has got edge. He's an anti-hero. And, there's also a vulnerability in there. There is conflict and battles going on in there.

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

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.

If you get too heavy with the nods and winks, people get a sense that they're excluded from something. If they're in screenings and everyone's laughing, and they don't know what the hell it's about, somehow you feel excluded from the party, or like you're not in the inner circle. As a performer, that's the worst thing you can do to an audience. It's fun, but you have to be very careful with it.

I find that kid actors are great reminders of the simplicity of acting. As you get older, you can sometimes complicate things a little more. You can become too aware of, 'Okay, this is the scene emotionally. This is where we need to be. We've got the climax coming up.' You can start to analyze it too much.

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.

I'm lucky to have worked in theater all over the world, but there's something magical about Broadway. The audiences are smart, they're educated. They go in ready and they're up for it, they're up for the party. It's a whole different atmosphere.
