A Connecticut Yankee in King Arthur's Court is a 1921 American silent film adaptation of Mark Twain's 1889 novel A Connecticut Yankee in King Arthur's Court. The film was produced by the Fox Film Corporation (later 20th Century Fox) and directed by Emmett J. Flynn based on a screenplay by Bernard McConville. It is notable as the first film adaptation of Twain's novel and as the second film about time travel to the past (after The Ghost of Slumber Mountain). The film is incomplete in the Library of Congress, and only reels 2, 4 and 7 survive.
