We've seen Duck Soup a number of times before but are always happy to see it again. When The Husband saw it mentioned on the yahoo political satire list he thought that was the perfect excuse to get out the DVD.
Duck Soup is a 1933 Marx Brothers political farce. "This means war!" It has the famous mirror scene (see it in part 6 below) that was imitated in I Love Lucy, and the last segment of the war with Firefly's constant un-noted uniform changes is hysterical. The movie is #85 on the 1998 edition of the AFI top 100 films list. On the 2007 update of the list it has moved up to #60.
Duck Soup is online in segments at youtube, but embedding of part 1 is diabled. part 1, part 2, part 3, part 4, part 5, part 6, part 7, part 8 and part 9
Senses of Cinema has a page on this film which begins, "Duck Soup is indisputably the Marx Brothers' greatest film." Roger Ebert considers it a Great Movie saying, "The Marx Brothers created a body of work in which individual films are like slices from the whole, but "Duck Soup" (1933) is probably the best."
11/16/2008: Edward Copeland on Film has an article on the celebration of the 75th anniversary of the film's release.
