It’s not a requirement to eat animals, we just choose to do it, so it becomes a moral choice and one that is having a huge impact on the planet, using up resources and destroying the biosphere.

You don't rest well as long as you're seeking vengeance. I feel sad justice wasn't done, but it's time to move on and sleep well.

The quickest way to destroy ocean science is to take human explorers out of the water

A director's job is to make something happen and it doesn't happen by itself. So you wheedle, you cajole, you flatter people, you tell them what needs to be done. And if you don't bring a passion and an intensity to it, you shouldn't be doing it.

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.

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.
