While filming at the Lewis Douglas ranch near Sonoita Arizona, Jack Lemmon had to spend long periods of time in the freezing water for a dunking scene on an extremely cold day in November 1955. He almost came down with hypothermia.
This is a remake/musical adaptation of Sucedió una noche (1934) from the same story "Night Bus" by Samuel Hopkins Adams and screenplay by Robert Riskin.
The character Danker is played here by Jim Backus. In Sucedió una noche (1934), Danker was played by Alan Hale, the father of Backus' future La isla de Gilligan (1964) co-star Alan Hale Jr..
One of several musicals made by Columbia Pictures in the mid-1950s that were based on earlier, non-musical studio properties. While this one spawned from Sucedió una noche (1934), Amor a medianoche (1953) was a musicalization of The Awful Truth (1937), and Sobra un marido (1955) was based on Demasiados maridos (1940). Another musical remake was more inadvertent: Columbia had planned to make the film version of the 1953 Broadway hit "Wonderful Town," which had been based on the Columbia property Los caprichos de Eileen (1942), but the asking price for the rights was so steep that the studio ultimately decided to go ahead with its own version, keeping the original title, which they already owned, and commissioning a new score.
