A Connecticut Yankee in King Arthur's Court is a 1949 American comedy musical film directed by Tay Garnett and starring Bing Crosby, Rhonda Fleming, Sir Cedric Hardwicke and William Bendix.

[4] Based on the novel A Connecticut Yankee in King Arthur's Court (1889) by Mark Twain, the film is about a mechanic in 1912 who bumps his head and finds himself in Arthurian Britain in 528, where he is befriended by a knight and gains power by judicious use of technology.

When he falls in love with the king's niece, her fiancé Sir Lancelot takes exception, and when he meddles in the politics of the kingdom, trouble ensues.

Filmed from October to December 1947,[5] A Connecticut Yankee in King Arthur's Court was released on April 22, 1949 and distributed by Paramount Pictures.

Hank begins introducing modern flourishes such as jazz music, safety pins, firearms and simple machinery as he attempts to romance the beautiful Alisande la Carteloise and to start a friendship with Sir Sagramore.

[11][12] The following week, with children out of school and the theater opening at 7:45 a.m. to enable six showings a day, it grossed a Radio City Music Hall record of $170,000 and became the number-one film in the United States.

It is a pleasantly fabulous excursion in the dream classification, and the cutback to the medieval past is effectively enough introduced in this adaptation of the Mark Twain story.

"[18] John McCarten of The New Yorker wrote that Crosby was "effortlessly amiable," but that the film lacked the wit of the 1931 Will Rogers version and that the songs were inferior to those of the Rodgers and Hart stage musical.
