Much of Los Angeles' past is lost to history -- but we can rediscover it in the region's archives. This new series, a co-production of KCETLink and the USC Libraries, in collaboration with "L.A. as Subject," brings Southern California history to life by marrying archival materials with innovative forms of documentary storytelling. Hosted by L.A. public historian Nathan Masters of USC Libraries, this original series of three episodes showcases nine emerging filmmakers. From rotoscoping to cinema verité, the range of the filmmakers' techniques mirrors the diversity of their backgrounds. But a common thread runs through their films: each brings the primary sources of Los Angeles history to the screen in surprising new ways. What previously hidden stories will the next generation of filmmakers unearth in the collections of "L.A. As Subject" members? Tune in to find out. Each episode of Lost L.A. rediscovers a forgotten city that preceded the arrival of Anglo settlers and shows how it transformed so quickly into a sprawling, culturally diverse metropolis.
