If I could only do one exercise, it would be dead lifting. For cardio, I dance, I ride my bike, I run and I have kids. There is a... lot of cardio just from being a parent.

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.

I like the Rolling Stones for karaoke. 'Sympathy For The Devil' is a great one.

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.

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.

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 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.
