Filming
The movie was filmed in March 1941, by Darryl Zanuck, on spring snow. The film became a Hollywood hit, and served as a recruiting effort for the elite ski corps of the 10th Mountain Division stationed at Camp Hale in Colorado. Sun Valley's ski school director, Otto Lang, of St. Anton, oversaw the skiing scenes in the film. The musical numbers were recorded in stereophonic sound and have been included in home video releases of the film.
