Avatar is the most high tech film in terms of its execution, dealing with essentially a very low tech subject; which is our relationship with nature...and in fact the irony is that the film is about our relationship with nature and how our technological civilization has taken us several removes away from a truly natural existence and the consequences of that to us.

Here's my philosophy in life: If there's a fire, you put it out. If there's a flood, you fill sandbags and you build a dike. You roll up your sleeves and you get to work.

I'm a curious guy. I can't turn away from an investigative story, when it comes to the forensic analysis. I've done 33 dives, to the titanic wreck site. I've spent over 50 hours piloting robotic vehicles at that wreck trying to piece together what happened during the disaster. How the ship broke up, comparing the historical record with the forensic record. Documentaries are kind of my new life. I love documentary filmmaking.

The literature now is so opaque to the average person that you couldn't take a science-fiction short story that's published now and turn it into a movie. There'd be way too much ground work you'd have to lay. It's OK to have detail and density, but if you rely on being a lifelong science-fiction fan to understand what the story is about, then it's not going to translate to a broader audience.

I guess Titanic because it made the most money. No, I`m kidding. I don`t really have a favorite. Maybe Terminator because that was the film that was the first one back when I was essentially a truck driver.

I've sworn off agnosticism, which I now call cowardly atheism. I've come to the position that in the complete absence of any supporting data whatsover for the persistence of the individual in some spiritual form, it is necessary to operate under the provisional conclusion that there is no afterlife and then be ready to amend that if I find out otherwise.

To convince people to back your idea, you've got to sell it to yourself and know when it's the moment. Sometimes that means waiting. It's like surfing. You don't create energy, you just harvest energy already out there.
