Family Flicks The Marx Brothers’ 1933 comedy masterpiece Duck Soup is chockablock with slapstick, but the themes of the political satire run deep and surprisingly topical. The marvelous Margaret Dumont co-stars as the millionaire widow who finances the political shenanigans. Younger children will enjoy the physical humor and gags; older children might be ready for a post-movie talk on the implications of nationalism. Directed by Leo McCarey, who added the oft-imitated mirror scene. UCLA Film & Television Archive, Billy Wilder Theater, Hammer Museum, 10899 Wilshire Blvd., Los Angeles, (310) 443-7000. Sept. 24, 11 a.m. Free.
