It stars Betty Grable, with support from John Payne, Carmen Miranda, Cesar Romero, Charlotte Greenwood, and Edward Everett Horton.

During the thirty-fourth week of their hit Broadway show, dancer Vicky Lane awaits the arrival of her partner, Dan Christy, but as usual, he is late.

Fed up with Dan's womanizing and insensitivity, Vicky quits the show and returns to her former dancing partner and beau, Victor Prince, who is still in love with her.

Dan is pessimistic, for Vicky and Victor are beginning a new engagement with Harry James and His Music Makers at the famous Lake Louise resort in the Canadian Rockies.

When Dan awakens sometime later, he finds himself at the Canadian resort and learns that he has hired McTavish as his valet and Rosita Murphy, who was working in the souvenir shop at the Detroit airport, as his secretary.

An article published by The Hollywood Reporter noted that Frederick Jackson was working on the picture's script, but the extent of his contribution to the completed film has not been confirmed.

According to a 20 December 1941 story outline, contained in the Twentieth Century-Fox Produced Scripts Collection at the UCLA Library, Fred Astaire and Rudy Vallée were originally considered for the male leads.

According to the Records of the Legal Department, also at UCLA, the studio paid $1,000 for a waiver from Villa Moret Inc., holders of the copyright to the song "When It's Springtime in the Rockies", for the use of the title.

A 22 June 1942 studio press release noted that the songs "Magazines" and "I Like to Be Loved by You", by Mack Gordon and Harry Warren, were to be included in the film, but they were not in the finished picture.

"I Had the Craziest Dream", which is sung by Harry James's band singer Helen Forrest in the film, became one of Betty Grable's signature songs.
