Jed Potter (Fred Astaire) is a popular radio personality who was once a famous dancer. He also used to be friends with Johnny Adams (Bing Crosby) until they became rivals for the affections of Mary O'Hara (Joan Caulfield). Jed lost out when Johnny and Mary got married, but life hasn't been too rosy for the couple since; Johnny's career in business was a washout, and not long after the birth of their daughter, the couple decided to divorce. Mary gave Jed another chance with her, but in time she chose to patch things up with Johnny, leading Jed to a close partnership with alcohol that ended with an accident, preventing him from ever dancing again. However, the aftermath of this tragedy helps bring the three former friends back together. Blue Skies was not much more than a framework for a bunch of musical numbers featuring great tunes from the Irving Berlin catalog, but when you've got Bing singing and Fred dancing to songs like "Puttin' on the Ritz," "You Keep Coming Back Like a Song," "A Couple of Song and Dance Men," and "White Christmas," why carp? Noted stage actor and tap dancer Paul Draper was originally cast as Jed, but he was fired after several days of filming and replaced by Astaire; Draper would make only one more movie before his film career came to an end after he was branded a Communist sympathizer.
