I do an awful lot of scuba diving. I love to be on the ocean, under the ocean. I live next to the ocean.

Failure is an option, fear is not.

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

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.

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.

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.

We have a great responsibility. Whatever we make will become the truth, the visual reality that a generation will accept.
