Live Poll: The National Film Registry's Elite Directors

The United States National Film Preservation Board created the National Film Registry in 1988 to preserve films which are "culturally, historically or aesthetically significant". Every year up to 25 films are selected and they range the gambit from experimental films and shorts to epic feature films spanning the last one thirty years of cinema.
