Old Rose: It's been 84 years, and I can still smell the fresh paint. The china had never been used. The sheets had never been slept in. Titanic was called the Ship of Dreams, and it was. It really was.

I want to challenge all of you as people of deep conscience, people who are environment stewards of the earth and oceans ... By changing what you eat, you will change the entire contract between the human species and the natural world.

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 tried [being a mogul]. It bores me. I don't really want to produce other people's movies. Because they're either grown-up filmmakers like Steven Soderbergh or Kathryn Bigelow that didn't really need me - and I've produced both of them. It's fun to sit around with them and be collegial, but they don't need me. They can make the film without me. I make my own stuff. There are tons and tons of other things I'm interested in that have nothing to do with movies or are documentary projects.

Don't get seduced by your own stuff. Don't get high on your own supply. The hardest thing as a filmmaker is when you're watching a film that you've worked on for several years. You know every frame so intimately that holding lots of the objectivity of a new viewer who has just seen it for the first time is the hardest thing. Every aesthetic decision you make - and you make thousands of them every day, have to - in theory, must be done from you being a blank slate. You almost have to run a program, like a mind wipe, every time you watch the movie.

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

Hope is not a strategy. Luck is not a factor. Fear is not an option.
