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.

Getting the audience to cry for the Terminator at the end of T2, for me that was the whole purpose of making that film. If you can get the audience to feel emotion for a character that in the previous film you despised utterly and were terrified by, then that's a cinematic arc.

I probably spend more time writing than reading science fiction. I find that science-fiction literature is so reactive to all the literature that's gone before that it's sort of like a fractal. It's gone to a level of detail that the average person could not possibly follow unless you're a fan. It iterates upon many prior generations of iterations.

Don't get seduced by your own stuff; work hard to keep a blank slate state of mind each time you watch your film.

There are many talented people who haven't fulfilled their dreams because they over thought it, or they were too cautious, and were unwilling to make the leap of faith.

If you set your goals ridiculously high and it's a failure, you will fail above everyone else's success.

The nation that leads in renewable energy will be the nation that leads the world 10, 20 years from now.
