When I was very young, biology, the diversity of life, was one of my main interests. I know there's this image people have that I'm this spoiled, cocky punk of an actor. Honestly, that's not who I am. I really care that so many species have been wiped out, like genocide of entire races. I believe in the divine right of all species to survive on this planet. So I decided I want to be active as an environmentalist. I learned. I asked experts. I got active.

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.

As far as my own dreams, I'm not a big dreamer, I think obviously we suppress things in life, emotions and thoughts, and we should wake up and look at that.

I got everything I need right here with me. I got air in my lungs, a few blank sheets of paper. I mean, I love waking up in the morning not knowing what's gonna happen or, who I'm gonna meet, where I'm gonna wind up. Just the other night I was sleeping under a bridge and now here I am on the grandest ship in the world having champagne with you fine people. I figure life's a gift and I don't intend on wasting it. You don't know what hand you're gonna get dealt next. You learn to take life as it comes at you... to make each day count.

You see, I think negative emotions are always trumped by positive emotions.

I like doing things that scare me. I went bungee jumping, but sky diving is just the sickest thing.

I'm not a big dreamer. I never have been. I remember fragments of my dream, and I try to take a traditional sort of approach to researching this project and doing preparation for it.
