David Fincher's latest movie The Killer features several references and details that point to other classic films as well as his signature directorial style. Michael Fassbender stars as the ruthlessly cold and calculated unnamed assassin who had a flawless reputation before making a costly error during a planned hit in France. The film consists of several Fincher-isms in its narrative structure, cinematography, themes, and frequent collaborators, constructed with a similar meticulous perfectionism as its eerie, unblinking protagonist.
