It's always been difficult for me to find funding for a story that I want to follow in real time. Financiers are hesitant to support a project when they don't know the outcome.

If you love your craft there will be passion. Most of my films are with people who are really passionate about what they are doing and know how to do something well.

Crowdsourcing is an invaluable resource for filmmakers, but be prepared for an enormous amount of work.

When Steve Wise told me that he intended to argue in court before a judge that an animal could be a "legal person," it seemed like a novel, possibly far-fetched idea, but the more I thought about it, the more I became intrigued.

When I was growing up in the '50s, I had never heard of a "woman film director," so I did not consider it as an option. But I was fortunate that in the late-'60s and '70s, because of the feminist movement, women were stepping into all sorts of careers that had been closed to them in the past and film was one of them.

Even after forty years of directing, shooting and editing films, when I collaborate with a male partner, people still perceive the man as the primary filmmaker.

I have always felt that documentaries are an opportunity for me to witness a world that I know nothing about.
