Basically, I think 21st century conservation is moving toward preserving ecosystems by dealing with the needs of people.

I don't flatter myself - I'm not a scientist, I'm not a conservation expert.

You can't control everything that comes to you.

I never even considered comedy genre as something to embrace or move away from.

Remarkably, there's no green screen in 'Leaves of Grass' movie. There is motion control. Technically, there were all sorts of challenges, but really the soul of it is Edward Norton talent. You write these characters when you write a movie, and all you can hope for or depend on is that your actors will elevate the material.

I come from a family of conservation activists, and so I've had a strong connection to nature all my life. My father has been a leader within the movement for over thirty years and has taught most of what I know about environmental conservation. While he would always take me hiking, camping, and rafting, he also taught me that the spiritual value of the outdoors alone is not enough to save nature against economic interests.

Fame is very corrosive and you have to guard very strictly against it.
