Filmmaking is a tool whose function has a range of diversity equal to that of the artist. It can exist as internal reflection, social commentary and activism, and with the possibility of transforming the world one audience member at a time. The means of distribution, and often production, tend to be in the hands of a few members of the large corporate media system. This puts limits on people who attempt documentary filmmaking with revolutionary goals, mostly because it may challenge the very foundations these systems are resting on. The underground may be the place for these digital video anarchists, where the rules are different and the dangers are more vivid. Guerrilla filmmaking, especially with non-fiction, is reproducing at rapid rates these days because of internet self-distribution and it is easy for truly independent filmmakers to get their work seen. If someone is attempting to by pass the normal flow of film distribution and ownership laws they may attempt to go anonymous, leaving the film to speak for itself without credit given to them explicitly.
