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.

There comes a certain point in life when you have to stop blaming other people for how you feel or the misfortunes in your life. You can't go through life obsessing about what might have been.

As an actor, you have many tools - your body, your voice, your emotions, mentally. In film, you have your eyes because they communicate your thought process. In fact, generally in film, what you don't say is more important than what you say. That's not so much the case for stage.

Comic book fans have loved Wolverine, and all the 'X-Men' characters, for more than the action. I think that's what set it apart from many of the other comic books. In the case of Wolverine, when he appeared, he was a revolution really. He was the first anti-hero.

I truly believe that the job of an actor and the drive of an actor is simulating the internal journey in life which is to get deeper and deeper into our understanding of who we are.

I tended to favour the piano over the guitar because it stays in one place, which is what I like to do.
