Loretta Young had a romance with Clark Gable while making this film, resulting in the birth of an out-of-wedlock daughter, Judy Lewis. For years, Ms. Young claimed she went away for a while, found the girl and adopted her. In 1994, Judy Lewis revealed the truth (which had long been the subject of speculation because of her resemblance to both parents) in her book "Uncommon Knowledge".
Like many films of the era, this production was originally slated to film in the Southern Sierra Nevada near Sonora. In fact, production had already begun when a warm front melted the snow and forced a hasty and expensive move to Washington state.

In 1992 Time-Life released a series of year-by-year CD compilations of the top rock 'n' roll hits of the year. On the front cover of the 1958 edition is a Fonzie-like character in white T-shirt and black leather jacket on a motorcycle. There is a movie marquee in back of him anachronistically advertising Clark Gable and Loretta Youg in "The Call of the Wild."
