The Wagons Roll at Night

The Wagons Roll at Night is a 1941 circus film directed by Ray Enright, starring Humphrey Bogart as traveling carnival owner Nick Coster, Sylvia Sidney as his girlfriend, and Eddie Albert as a newcomer who falls in love with Nick's sister, played by Joan Leslie. The screenplay is by Fred Niblo Jr. and Barry Trivers, and the film is based on a 1936 novel by Francis Wallace, first published as a serial in The Saturday Evening Post. This film marks the only instance to date when the story was presented using its original circus setting, as Wallace's novel was the basis for the earlier 1937 film Kid Galahad, directed by Michael Curtiz - also by Warner Bros. and featuring Bogart in a supporting role - but using the boxing world as a backdrop. In 1962, United Artists produced a musical remake of the "boxing" version of Wallace's story under the same title, directed by Phil Karlson and starring Elvis Presley as the boxer.
