I'm not doing any crazy stuff any more. Like I used to do high falls; I used to jump from the motorcycle to the truck myself. That's unheard of today. Now nobody would ever do that. In those days it was stupid, man. I just did it because that's what it was, but that I don't do anymore.

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.

I found out about it probably 9 - 10 months before we shot the film [Don't Kill It] because it was postponed a couple of times, which was actually a good thing because once it all finally came together, I had to get in there and roll off different pages of dialogue and monologues pretty quickly.

I got good grades in school, but I'm not sure if I'm smart or if it just means I can study. I've never taken one of those IQ tests, and I don't want to. It's so pointless. As long as you enjoy life and have fun and you're healthy and happy, that's what matters.

You really have to work hard to create a three-dimensional character. You have to rehearse and explore and take your time. You can't just memorize your lines and do it on the fly.

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.

No one can believe I might have a brain. Because I'm really tall, I'm really blonde, I have big muscles, and kill people for a living. There you go. If anybody's going to be assumed to be stupid, it's me. I don't know what my IQ score is, but I did study for five years at college. And I'm proud of my chemical engineering degree. I haven't done anything with it, but it's a card up your sleeve for later in life. It's nice to have, just in case.
