Every year the Library of Congress selects 25 films for preservation in the National Film Registry, based on their value as “cultural, artistic, and historical treasures.” James H. Billington, Librarian of Congress, recently announced the list for 2009; among the inductees are Sidney Lumet’s Dog Day Afternoon (1975), Kent Mackenzie’s The Exiles (1961), Jack Arnold’s The Incredible Shrinking Man (1957), William Wyler’s Jezebel (1938) and Mrs. Miniver (1942), Rouben Mamoulian’s The Mark of Zorro (1940), Sergio Leone’s Once Upon a Time in the West (1968), Michael Gordon’s Pillow Talk (1959), William Wellman’s The Story of G.I. Joe (1945), and, in honor of Michael Jackson, John Landis’s 1983 video for Thriller.
