I think documentary filmmakers need as much protection as possible under journalist's privilege. How else is the public to know what is going on?

San Franciscans are very proud of their city, and they should be. It’s the most beautiful place in the world.

I was raised in California during the Second World War and into the '50s and everything was fine, everything was great. The sun always shone, everybody looked healthy and wore ties and smoked in restaurants, and there were cars for everybody - except us, because I came from a lower class neighbourhood. But [in France] I realised there was a different point of view, so when I came back to America a year and a half later I was much more focused on my own country culturally and politically.

You’re never going to be the same person you are right now.

It's all about greed and money and it's the driving force in Hollywood.

Politics right now is in a very dark place, and I think the only place for me is to do what I do - make films, create art, watch it as it evolves. Right now it's like Humpty Dumpty sitting on a wall, and a great fall is happening. The behavior seems to be really dumb.

I would see my hometown, Los Angeles, change. Green space and orange groves gave way to cement, freeways flooded with traffic, and air pollution, all in the name of "progress." I felt like I was losing my home. It had a profound effect on me, and I realized just how important nature was to my spirit, my soul, my point of view.
