Joel and Ethan Coen, known as The Coen Brothers, are Oscar-winning American filmmakers. For more than 20 years, the pair have written and directed numerous successful films, ranging from comedies (O Brother, Where Art Thou?, Raising Arizona, The Big Lebowski) to film noir (Miller's Crossing, Blood Simple, The Man Who Wasn't There), to movies where those two genres blur together (Fargo, Barton Fink). The brothers write, direct and produce their films jointly, although until recently Joel received sole credit for directing and Ethan for producing. They often alternate top billing for their screenplays, while sharing film credits for editor under the alias "Roderick Jaynes". They are known in the film business as "the two-headed director", as they share such a similar vision of what their films are to be that actors say that they can approach either brother with a question and get the same answer.
