I get a friend to travel with me... I need somebody to bring me back to who I am. It's hard to be alone.

There's so many intangible forces that come into play when making a film, I have no idea what the public will ultimately think of something that I do, let alone critics.

I don't think there's a specific science you can put on dream psychology. I think that it's up to the, obviously, the individual.

If you're gonna let the character be the story, you better set a tone that allows the actors to do the best work they can do.

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.

I know a lot of the intense moments in 'Titanic' were made that much easier and were pushed to even further limits because of that relationship.

I'm never really conscious of saying, "I'm going to take on a specific role to combat a certain image in the public eye." I think that's pretty manipulative and transparent to the public anyway.
