Forget the guilt trip, the Green Film Festival of San Francisco, the mischievous, tree-hugging cousin of the 29 year old SF IndieFest, returns Oct 15-22 to prove that saving the planet doesn't have to feel like homework. We've ditched the doom-and-gloom documentaries that make you want to crawl under a (sustainably sourced) blanket and never come out. The line-up this year pairs sharp environmental storytelling with wit, weirdness, and unapologetic irreverence.
