As Wolstenholme says "the time has come" for the natural and organics market in South Africa. He adds: "The agreement by Mann and Harrelson to show the film for the first time in South Africa is recognition of the potential of SA consumers to make the shift from destructive practices and products to sustainable alternatives".

An Academy Award nominee for his role in "The People Vs Larry Flint", Harrelson (known to most of us as Woody in Cheers and in his infamous role in “Natural Born Killers”), has an impressive CV for the stage and screen. He has also come to personify the search for an organic, healthy and holistic lifestyle in the United States and is known as one of Hollywood's most vocal and controversial environmental activists.

As he commented in a recent interview: “I’ve been concerned (about living the organic lifestyle and the environment) for years. When I was in seventh grade I did a report about the environment and the loss of species. It was supposed to be only a few pages, but ended up being nearly 50. I’ve always had an intense relationship with nature, something which I think all of us have somewhere inside us”.

Mann’s film, described by the Toronto Sun as the next "Bowling for Columbine", traces the actor’s “Simple Organic Living Tour 2001” from Seattle to Santa Barbara. Harrelson and a buddy cycled most of the way with the back-up gang, including his raw-food chef and a yoga instructor, following in a hemp-fuelled bus.

The serious message that Woody takes to the universities down the coast, that mankind can still halt destruction of the planet and strike a balance between economic growth and ecological sanity, is leavened with a good dose of humour.

There are also pop-video style interludes from eco-minded musicians Bob Weir, Michael Franti, Nathalie Merchant, Anthony Keidis, Medeski Martin and Wood, String Cheese Incident, and South African Dave Matthews.

Canadian national Mann, who previously made alt propaganda doc Grass, mocking the US government’s war on pot, throws the rulebook on documentary making in the garbage can. His 1981 documentary "Imagine the Sound", which traced the free jazz movement of the 1960s won instant acclaim. He followed this with “Poetry in Motion” (1982), an analysis of 24 contemporary poets, including William S. Burroughs, Charles Bukowski and John Cage.

Both men have expressed their delight at the premier screening of “Go Further” in South Africa. As Harrelson says in the film: "I sometimes feel like an alien creature for which there is no earthly explanation. In money we trust we'll find happiness-the prevailing attitude. Like a genetically modified, irradiated Big Mac is somehow symbolic of food. Morality is legislated, prisons overpopulated, religion is incorporated, the profit motive is permeated all activity. Can you imagine clean water, food and air? Living in community with people who care? Do you dare to feel responsible for every dollar you lay down? You gonna make the rich man richer or you gonna stand your ground? You say you want a revolution, a communal evolution, to be a part of the solution? Maybe I'll be seeing you around".
