Fred Astaire, then 47 years old, planned to retire as a leading man with this film. He was planning to only work with his dance studios and breed racehorses. Easter Parade (1948), having recently lost Gene Kelly to a broken ankle, brought Astaire out of retirement. He danced on film and on television until he was nearly 70.
The film begins in the late 1910s, and the costumes of Joan Caulfield, and other prominent female players, reflect a vague attempt to at least somewhat recreate the styles of that period, with ankle length hobble skirts, slit to the knee. But as the story progresses, through the 1920s and 1930s, the fashions never change, with Caulfield still wearing a similar ensemble 20 years later during the 'Blue Skies' number.
Irving Berlin's 'Puttin' on the Ritz' was written in 1929, and includes the name of 'Gary Cooper', a high ranking and popular newcomer, in the lyrics, but in this film it is supposedly performed in the early 1920s, several years before it was actually written, at which time Cooper was unknown, but the lyrics remain the same.
One of over 700 Paramount Productions, filmed between 1929 and 1949, which were sold to MCA/Universal in 1958 for television distribution, and have been owned and controlled by Universal ever since. It was released on DVD 6 May 2003, in tandem with Birth of the Blues (1941), as part of Universal's Bing Crosby Collection, and again 11 November 2014 as one of 24 titles in Universal's Bing Crosby Silver Screen Collection. Since that time, it's also enjoyed an occasional airing on cable TV on Turner Classic Movies.
