High Quality Content by WIKIPEDIA articles! Blue Skies is a 1946 Hollywood musical comedy film, released by Paramount Pictures and starring Bing Crosby, Fred Astaire, Joan Caulfield, Olga San Juan and Billy De Wolfe, with music, lyrics and story by Irving Berlin; most of the songs were recycled from earlier works. The film was directed by Stuart Heisler and produced by Sol C. Siegel. As in Holiday Inn (1942), the film is designed to showcase the songs of Irving Berlin. The plot, which is presented in a series of flashbacks with Astaire as narrator, follows a similar formula of Crosby beating Astaire for the affections of a leading lady. Comedy is principally provided by Billy De Wolfe. Joan Caulfield was the protege of Mark Sandrich - who directed many of the Astaire-Rogers musicals - and who was originally slated to direct this film. He died of a heart attack during pre-production and Stuart Heisler was drafted in to replace him. Heisler wanted Caulfield replaced, but Crosby - who was having an affair with Caulfield - protected her.
