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

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 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.

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.

To have memories of those you have loved and lost is perhaps harder than to have no memories.

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.

When lifting, I'm always with a trainer because the thing that makes a difference is that last 20% in your training, and he very scientifically looks after my food as well, because when I'm going for a 'shirt off' shot, everything changes the month before, and I'm timed down to the day.
