Nicholas Ray and Gloria Grahame met while shooting this film. They were married in Las Vegas shortly after completing the film. They chose Las Vegas because Ray loved to gamble and to allow Grahame to get a quickie divorce (after the required six weeks of residency in Nevada) from actor Stanley Clements. The day the divorced was granted, the two married.
Gloria Grahame's (uncredited) singing double in this film was Kaye Lorraine. Maureen O'Hara sang her own songs.
Completed in early 1948, but not released until nearly a year later in 1949 during the tumultuous ownership of RKO by Howard Hughes.
Of the five films produced by Herman J. Mankiewicz, this is the only one in which he openly received credit.
This film was a flop at the box office, resulting in a loss of $760,000 ($9.8M in 2023) for RKO according to studio records.
