Earlier this year a movie was released on DVD telling the story of a forgotten American war — the civil war between the people of northern and Southern California. The movie imitates a Ken Burns documentary, but it’s obviously fictional. The premise and the visuals are based on the work of an artist named Sandow Birk. Birk explains why he felt San Francisco and Los Angeles were destined to come to blows. Produced by Neda Pourang.
