Sleepy Lagoon is a 1943 American musicalcomedy film directed by Joseph Santley and featuring comedian Judy Canova and singer Dennis Day. The film was written by Prescott Chaplin, and Frank Gill, Jr. and George Carleton Brown wrote the screenplay. It was Canova's final feature for Republic until 1951.
The setting of the film, the fictional town of Sleepy Lagoon, was possibly inspired by the song of the same name, which was popular at the time. The content of the film, however, is totally unrelated to the Sleepy Lagoon murder, which took place at a now-defunct Southern California reservoir and led to the Zoot Suit Riots.
