When Doris Day's character is questioned by reporters about an affair she's supposedly having with S.Z. Sakall's character, one of them asks her, "Is it true you call him 'Cuddles'?" This is an inside joke, as Sakall's nickname in real life was "Cuddles".
Doris Day's 10-inch Columbia LP of selections from the film score captured first place on the "Billboard" pop albums chart.
The plot is a mix of Lady for a Day (1933) with the closing number an homage to the "Lullaby of Broadway" number in Gold Diggers of 1935 (1935).
When a 1957 accident involving a horse cut short his career as a dancer and leading man, Gene Nelson turned to working behind the camera, and amassed quite a list of directing credits, including two Elvis movies (Kissin' Cousins and Harum Scarum) and dozens of hit TV shows (including Star Trek and Fantasy Island).
Warner Brothers decided to elevate Gene Nelson to co-star status with Doris Day after Nelson won the 1950 Golden Globe for Best New Star for his appearance opposite Day and Gordon MacRae in Tea for Two.
