You can either be a vain movie star, or you can try to shed some light on different aspects of the human condition.

We've been given this gift, our planet, and we've found no other place in the universe that we can inhabit. I want to do something to create radical change to help save it. It's our responsibility.

Acting is the only time when I truly maintain the spontaneity that I want to be present at all times.

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.

We're at risk of losing this iconic species for all time. Once it's stripped of its natural instincts, it's no longer a tiger. But there's a lot of species like that. The more intriguing thing, throughout Asia, a lot of these countries are selling off their jungle-and-forest rights for oil and for paper-and-pulp companies.

I've always kind of made sure to maintain the sense of who I am and never be mean or cruel or snotty to anyone. Because, at the end of the day, it's not going to help you last in the business, and who wants to be around someone like that? I don't want to turn into 'that guy.' That guy!

When I grew up, I lived in the ghettos of Hollywood; it was the most disgusting place to be. I was known as the crazy little kid. I did impressions. Then I realized that's not what I want to do. I don't want to be a comedian to please other people.
