In 2001 Woody Harrelson went on a tour to promote environmentally-friendly alternatives to our destructive lifestyle. Travelling in a bio-fueled bus and on bicycles, they went down the Pacific coast of California and Ron Mann made a film about that tour. Go Further skillfully combines a road movie with personal stories about how you can change your lifestyle and change the world. The ideas within the film are more fully explained and explored at Woody Harrelson and Laura Louie's Voice Yourself site about sustainable living and reducing your environmental footprint. A film about doing the right thing can be didactic or boring, but Mann wisely builds the story of Go Further around people and their relationships. Instead of having the focus on Harrelson, it is on Steve Clark, who joins the tour and tries to give up his fast-food lifestyle. It's a fun and entertaining documentary that educates along the way. I had a lot of fun and it gave me a few ideas as well.
