Duck Soup  is the Marx Brothers' masterpiece, acclaimed not only for its brilliant comic routines but for its satire of nationalism, jingoism, and saber-rattling. There’s no plot to speak of here...mostly the setup provides a framework for some of their most memorable routines.
Billy Wilder’s Some Like It Hot  is such a beloved movie – in 2000 it was named the best Hollywood comedy ever in an American Film Institute poll – that few remember that the critics disliked it and that the studio didn’t want to make it.
