Cheerfully subversive, “Westsider” takes the viewer along the route of an unashamedly self-centered graduate of an L.A. architecture school who uses and abuses everyone in his path in order to attain his goal of becoming the next Frank Gehry-type superstar architect. A subtle and sarcastic portrayal of L.A. excess, naked ambition and misguided idealism, “Westsider” was shot guerrilla-style (without permits) in neighborhoods throughout Los Angeles county over a period of eight days.
