For too long we have been taking, and the Earth has been giving. But that free-for-all, that all-you-can-eat buffet, it's over. The salad bar is closed.

I was always writing about the connection between man and nature. I grew up in a neighborhood that was right on the beach, but the beach was not like a beach you would imagine - there was a lot of pollution. And the most magical thing to me as a kid was sea glass, so I wrote about that a lot.

I think I came to film-making through writing. I started to write, and people, teachers, responded to my writing.

My hope is that I'm going to continue to make more and more challenging work that's going to come out more and more interesting. I don't know if that will always continue to happen, but every one of my films has definitely been a progression as far as complexity of narrative, character, and plot.

Now there is so much expertise and brainpower it's hard to be at the cutting edge of what's cool and not do something that's totally geeky.

I feel that so many sci-fi films and films in general have just become really dependent on and addicted to CGI, and that some of the big CGI films of the summer, you see these effects that look like crap. You don't know if you're watching a cartoon or something that's real. And I didn't want to fall into that trap. I really thought there was a way to use a lot of these old techniques to do some new and really neat stuff.

I try to live my life where I end up at a point where I have no regrets. So I try to choose the road that I have the most passion on because then you can never really blame yourself for making the wrong choices. You can always say you're following your passion.
