Everybody's going to do the 3D slightly differently the same way that people are going to deal with color differently. Some movies downplay the color, some color is very vibrant. Color design is very different. We've got to think of 3D like color or like sound, as just part of the creative palette that we paint with and not some whole new thing that completely redefines the medium.

I'm certainly not a fan of conversion when you could shoot the movie in 3-D.

I'm willing to engage or indulge real ideas, but if we don't do something [about global warming], we're all going to die! What's it going to take, a big f--ing disaster with all kinds of people dying? We need to change our priorities fast.

Writing a screenplay, for me, is like juggling. It's like, how many balls can you get in the air at once? All those ideas have to float out there to a certain point, and then they'll crystallize into a pattern.

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 think people had somehow gotten the sense that we have explored everything, when that isn't the case. We so know so little about the ocean, and so much of it is being destroyed.

I certainly didn't think of myself as gifted. The standards for being gifted in my environment were if you were good in Little League or if you were good in football.
