Cinematical has just received this exclusive new poster for No Impact Man, a documentary directed by Laura Gabbert and Justin Schein. The film follows Manhattan-based author Colin Beavan as he makes a life-changing decision that affects not only himself, but his wife and infant daughter as well.

Researching his next book, he founded the No Impact Program in November 2006, and pondered what he could do personally to help end the environmental crisis. What would have the greatest impact -- or, rather, what would allow him to have the least impact? From the official synopsis: "A newly self-proclaimed environmentalist who could no long avoid pointing the finger at himself, Colin leaves behind his liberal complacency for a vow to make as little environmental impact as possible for one year. No more automated transportation, no more electricity, no more non-local food, no more material problem. That is, until his espresso-guzzling, retail-worshipping wife Michelle and their two year-old daughter are dragged into the fray." No Impact Man is "a film about a couple, more than a movement," wrote John Anderson in Variety. It's "the best kind of propaganda, as well as a very entertaining movie."

Oscilloscope Pictures will open No Impact Man in New York on September 11 before expanding it across the country in the following weeks. Check Oscilloscope's site for more information on playdates, and head to Beavan's blog to read much more about his experiences.
