Think of drastically different genres. Fuse some with others and add new elements. Borrow patterns, themes and impressions from the halls of movie history and blend them with postmodern philosophy, a wickedly self-deprecating sense of humor and a heavy dose of playful ironic detachment. The resulting mixture pays homage to directors such as Stanley Kubrick, Roman Polanski, Sam Raimi and Preston Sturges, and writers like  William Faulkner, Flannery O’Connor, James M. Cain and Raymond Chandler. I’m referring to none other than the work of Joel and Ethan Coen, the modern American maestros of cinematic cross-breeding.
