Climate change is critical to me because I'm a parent; I feel a sense of responsibility to the future. I'm not going to be around to see its worst effects, which are going to be hitting in the 2030s, '40s, '50s, but my kids will.

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.

Failure is an option, fear is not.

I tend to like strong female characters. It just interests me dramatically. A strong male character isn't interesting because it has been done and it's so cliched. A weak male character is interesting: somebody else hasn't done it a hundred times. A strong female character is still interesting to me because it hasn't been done all that much, finding the balance of femininity and strength. [From a 1986 Fangoria interview]

We have nightmares because our brain is running simulations to put us in jeopardy to see what we'll do or to acclimatize us to that idea that something bad could happen. It's just how human beings are wired because the entire time we were evolving we had to jump quick or the leopard would get us or whatever it was. It's Darwinian.

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 try to live with honor, even if it costs me millions of dollars and takes a long time. It's very unusual in Hollywood. Few people are trustworthy - a handshake means nothing to them. They feel they're required to keep an agreement with you only if you're successful or they need you.
