In writing the new films, I’ve come to realize that AVATAR’s world, story and characters have become even richer than I anticipated, and it became apparent that two films would not be enough to capture everything I wanted to put on screen.

It took me a long time to realize that you have to have a bit of an interlanguage with actors. You have to give them something that they can act with.

Everybody is always talking about droughts and sea level rise, but when human civilization, with more crowding and greater resource depletion, is under that much stress, it translates into wars and huge displaced populations. The Syrian refugee crisis is just a first taste of what it's going to be like. I don't want my kids growing up in that kind of world.

Literary science fiction is a very, very narrow band of the publishing business. I love science fiction in more of a pop-culture sense. And by the way, the line between science fiction and reality has blurred a lot in my life doing deep ocean expeditions and working on actual space projects and so on. So I tend to be more fascinated by the reality of the science-fiction world in which we live.

I think "Avatar" is kind of a unique category where people are enjoying the unique theatrical experience even though they may have seen it on the small screen. They want to have that immersive, transportive experience. "2001: A Space Odyssey" played for three years at the Loews cinema in Toronto. I remember that. It just kept playing. People wanted to return to that experience. That may not be the best example because I think "2001" took 25 years to break even.

I've tried not to get sucked into the Hollywood hierarchy system. Personally, I don't like it when people are deferential to me because I'm an established filmmaker. It's a blue-collar sensibility.

I lived in a small town. It was 2,000 people in Canada. A little river that went through it and we swam in the - you know, there was a lot of water around. Niagara Falls was about four or five miles away.
