The bread-and-butter of the film industry is the action movie. Each summer, audiences can expect to see car chases, gunfights and explosions, and studios can expect to see millions and millions of dollars in return. Though most viewers and critics see these movies as "fluff" entertainment, there is one director that puts as much heart and soul into his "fluff" as any number of talented directors put into their "serious" movies. His name is John Woo. Even though you may not have heard about him, he is widely considered to be the best contemporary director of action films working anywhere.
