The Killer is the latest genre masterpiece from director David Fincher. A stylish, globe-trotting thriller in which Michael Fassbender plays a nameless assassin on a quest for revenge. It's the latest entry in this rather storied sub-genre where style and substance often work hand-in-hand and allow filmmakers and performers to show off their technical prowess.
