Used to be there was one and only one: the venerable USA Film Festival, co-founded in 1970 by filmmaker L.M. Kit Carson. Now you can't shake a reel of film without hitting someone putting together a lineup of films making the fest-circuit rounds--that is, movies without distribution, and only a few worthy of it (for instance, the brilliant Tribute, a Soderbergh-exec-produced doc that played the USA Film Fest and the Dallas Video Fest this year but can't find a taker because of costly music licensing issues). Forthcoming in the days ahead are the Latino-centric Vistas Film Festival in October and the Deep Ellum Film Festival the next month; and in the mix are fests geared toward fans of gay and lesbian offerings and Asian imports.
