Which 1939 Frank Capra film stars James Stewart as newly appointed senator Jefferson Smith? The film is Mr. Smith Goes to Washington.

James Stewart plays Jefferson Smith, an idealistic newcomer appointed to the U.S. Senate. He becomes entangled in a corrupt political scheme involving a dam project and eventually fights back through a prolonged Senate filibuster. Jean Arthur plays Saunders, his sharp and initially skeptical secretary, while Claude Rains portrays Senator Joseph Paine.

Frank Capra directed the political comedy-drama from a story by Lewis R. Foster, with a screenplay by Sidney Buchman. The film’s optimistic portrait of an ordinary citizen confronting entrenched corruption provoked criticism from some politicians, who argued that it damaged Washington’s reputation.

The title is sometimes mixed up with Capra’s Mr. Deeds Goes to Town, another idealistic 1930s comedy. Mr. Smith Goes to Washington was not a sequel, though Capra briefly considered making it one. It became a major success, earned 11 Academy Award nominations, and won for Best Original Story.
