The way I deal with arthritis is to keep moving. As long as I can play hard tennis, as long as I can ski or ride a horse - all kinds of things can come your way. As long as you can, do it. People who retire die. My dad retired and died shortly after. Just keep moving.

Have a strong vision about the story you want to tell and how you want to tell it.

I'm not much interested in sport just as sport. I wouldn't be interested in making a golf film or baseball or fishing film.

I have a lot of land. I bought it because I had a very strong feeling. I was in my early twenties, and I had grown up in Los Angeles and had seen that city slide off into the sea from the city I knew as a little kid. It lost its identity - suddenly there was cement everywhere and the green was gone and the air was bad - and I wanted out.

Success is a tricky mistress. It's nice to have but it's a tricky thing to embrace.

I'm not that interested in someone that one-dimensional, but I'm interested in playing somebody that's more complicated.

Any time I saw people treated unfairly because of race, creed, whatever - it struck a nerve.
