I try to keep the martial arts up. It's a good thing, not just physically but also for your mind.

Hollywood is great for entertaining people, it's a wonderful business but it's make-believe, you must remember that. That's one of the most important things to remember and the distinction in your own life, otherwise people get lost in their own fame, and it makes them unhappy.

In my career, whether it's a big or a small movie, when I've worked on something for a long time, like [Ivan] Drago in Rocky IV, they start to take on a life of their own.

It takes nine months for a baby to develop, it takes nine months to develop a character.

Unless you're playing a real character based on a real person, if someone else has done it before, you're probably better off not watching it as an actor. Otherwise you end up trying to copy someone else.

Your body's made to run, to walk, to trek long distances and carry things, work in a forest, and hunt animals. You have to keep it alive to function.

I discovered martial arts, first judo and then karate, and I became quite good at it, because I had something to prove. And more than anything, I needed to feel safe.
