Go home, pick up your video camera, and make a film.

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.

So my message is in whichever realm, be it going into space or going into the deep sea, you have to balance the yin and yang of caution and boldness, risk aversion and risk taking, fear and fearlessness. No great accomplishment takes place, whether it be a movie or a deep ocean expedition, or a space mission, without a kind of dynamic equipoise between the two. Luck is not a factor. Hope is not a strategy. Fear is not an option.

Climate change is critical to me because I'm a parent; I feel a sense of responsibility to the future. I'm not going to be around to see its worst effects, which are going to be hitting in the 2030s, '40s, '50s, but my kids will.

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.

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

The film industry is about saying 'no' to people, and inherently you cannot take 'no' for an answer.
