Yoshihiro Nakamura makes movies that puzzle, surprise and illuminate their themes both cleverly and literally (the fireworks of "Golden Slumber," the comet of "Fish Story"). Everyone's heard of the "butterfly effect" — how a small action in one place (a butterfly flapping its wings in a South American jungle) can cause a large impact in another (a hurricane in Florida). But in "Fish Story" (2009), his masterpiece to date, Nakamura takes us brilliantly and entertainingly though the entire baffling process, in telling a multi-layered but finally satori-like story of how a long-forgotten punk band's song saves the world.
