The main hotel set had been used some months previously in Annie Get Your Gun (1950). Clinton Sundberg appeared as the hotel manager in both films. In the same "waste not, want not" tradition, some of the "Annie" costumes were also reused.
One of the main plot points in the movie is that Phyllis Kirk's character is two years older than Jane Powell's character. This was a fact in real life. Phyllis Kirk was born in 1927, Jane Powell was born in 1929.
