I was this Swedish kid who came over here to study engineering, but I got into movies, and suddenly I'm in this 'Rocky' picture with Sylvester Stallone. And then the movie comes out, and it's a big hit, and I'm famous. Like, world famous. I wasn't thinking of ruling Hollywood; I was thinking of just trying to make it to the next day, trying to figure out what the hell happened.

I think by planning an exercise regime, your diet follows to some extent.

I think mortality makes you live a fuller existence. When I was a kid I was scared of death, and maybe that's what made me desperate to get the most out of life.

I think the energy I give off is quite non-confrontational. That's something you learn from karate. Once you try to be a tough guy, you've got to pay up. You've got to prove yourself. And that's exhausting.

There are a lot of great athletes who stop working out, and they get out of shape like everybody else in their 30s and 40s.

At least once a week, I try to have one day where I have nothing planned so I can get up and just go back to bed and lay around and recharge my batteries.

My sensei was a British karate champion named Brian Fitkin. He was my mentor and because I had a hard relationship with my dad, he became a father figure to me.
