In an interview in the New York Times, James Cameron (director, deep see explorer, Planetary Resources financial backer) says,

I don’t find my inspiration in movies. I find my inspiration in life – in the natural world, in daily life.

...

I’ve divided my time over the last 16 years over deep ocean exploration and filmmaking. I’ve made two movies in 16 years, and I’ve done eight expeditions. Last year I basically completely disbanded my production company’s development arm. So I’m not interested in developing anything. I’m in the “Avatar” business. Period. That’s it. I’m making “Avatar 2,” “Avatar 3,” maybe “Avatar 4,” and I’m not going to produce other people’s movies for them. I’m not interested in taking scripts. And that all sounds I suppose a little bit restricted, but the point is I think within the “Avatar” landscape I can say everything I need to say that I think needs to be said, in terms of the state of the world and what I think we need to be doing about it. And doing it in an entertaining way. And anything I can’t say in that area, I want to say through documentaries, which I’m continuing. I’ve done five documentaries in the last 10 years, and I’ll hopefully do a lot more.

...

My reality is that I’ve made two films in the last 15 years that both have been resounding successes here, and this is an important market for me. And so I’m going to do what’s necessary to continue having this be an important market for my films. And I’m going to play by the rules that are internal to this market. Because you have to. You know, I can stomp my feet and hold my breath but I’m not going to change people’s minds that way.
