It was invaluable to have a dear friend who you have known for over a decade, be a partner in a film like Titanic. To have somebody that talented to work against, who's also your friend and who you know you have the best intentions for and vice versa, and who you intrinsically trust to give you their forthright honest opinion about what we're both doing - all that's something you can't really buy.

I have no problem playing anyone who has different politics than me. In fact, I don't take that into consideration at all. You have to find something sympathetic in a man. It's that common ground you need to connect with someone.

You never know as a director what other directors do. Because you don't get to see what they do.

When I was eighteen, River Phoenix was far and away my hero. Think of all those early great performances - My Own Private Idaho. Stand by Me. I always wanted to meet him. One night, I was at this Halloween party, and he passed me. He was beyond pale - he looked white. Before I got a chance to say hello, he was gone, driving off to the Viper Room, where he fell over and died. That's a lesson.

Dreams feel real while we're in them. It's only when we wake up that we realize something was actually strange.

Fame is not the worst thing. I went to dinner the other night, and the girls in the restaurant ignored me. It was so annoying.

I became an actor at a very young age, but I also had a deep respect for nature and I think I was sort of a little biologist when I was younger. I watched documentaries on rainforest pollution and the loss of species and habitats for animals around the world. It affected me in a very hardcore, emotional way when I was younger. So, later in life I wanted to continue that path more and investigate and learn more about ecological issues.
