Writing a screenplay, for me, is like juggling. It's like, how many balls can you get in the air at once? All those ideas have to float out there to a certain point, and then they'll crystallize into a pattern.

There is a vast frontier that's going to take us a while to understand... it was very lunar, a very desolate place, isolated.

I think people had somehow gotten the sense that we have explored everything, when that isn't the case. We so know so little about the ocean, and so much of it is being destroyed.

Every time my cameras go out on a movie, we learn something new and then we take what we learn and we put it into the next generation of the cameras so we're constantly improving. It's kind of like building a race car, racing it, then running back to the shop and working on the engine some more and tinkering with it to improve it.

To convince people to back your idea, you've got to sell it to yourself and know when it's the moment. Sometimes that means waiting. It's like surfing. You don't create energy, you just harvest energy already out there.

I certainly didn't think of myself as gifted. The standards for being gifted in my environment were if you were good in Little League or if you were good in football.

I'm hopeful that we'll be able to study the ocean before we destroy it.
