Three days, nine films, eight shorts, and endless bliss courtesy of last weekend's fourth annual 3rd I South Asian Film Festival. This year's lineup showcased a wide range of tastes. Opening night at San Francisco's Yerba Buena Theater Friday started off with a super rare screening of British Asian Dub documentary "Foundation & Empire," followed by a local South Asian Shorts, featuring a Q&A that included every director in attendance.
