Mr. Smith Goes to Washington is an American 1939 comedy/drama film starring James Stewart and Jean Arthur, about one man's effect on American politics. It was directed by Frank Capra – his last film for Columbia Pictures, the studio where he made his name – and written by Sidney Buchman, based on Lewis R. Foster's unpublished story. Mr. Smith Goes to Washington was controversial when it was released, but also successful at the box office, and made Stewart a major movie star. Aside from Stewart and Arthur, the film features a bevy of well-known supporting actors, among them Claude Rains, Edward Arnold, Guy Kibbee, Thomas Mitchell and Beulah Bondi. Mr. Smith Goes to Washington was nominated for 11 Academy Awards, winning for Best Screenplay.
In 1989, the Library of Congress added Mr. Smith Goes to Washington to the United States National Film Registry, for being "culturally, historically, or aesthetically significant."
