We are about to head into a flurry of film festival activity. The next two months will see the Imperial Beach Film Festival, The San Diego Film Festival, The San Diego Women Film Festival and The San Diego Asian Film Festival, not to mention a film series starting at the San Diego Natural History Museum. Anyway, to kick off this festival season is the Fourth Annual Imperial Beach Film Festival (running September 8 and 9 with the Dempsey Holder Hall as their main screening site).
