Springtime in the Rockies was a significant hit for the era and especially for Betty Grable. Altogether, it managed to pull in just over 2 million dollars, which is around 34 million dollars today. That might not sound like much. However, it was enough to make it one of the top ten films of 1942. It was even popular enough to catch the eye of Disney, who had Donald Duck quacking a version of the lead song while in the bath. The story was initially filmed under the title Second Honeymoon with the director Walter Lang.
