Roy Del Ruth was originally assigned to direct, but he quit over creative differences with producer Erich Pommer, so Dorothy Arzner was assigned the job.
Lucille Ball and Maureen O'Hara became inseparable friends while shooting this film, and remained lifelong friends until Ball's death in 1989. O'Hara was having lunch with her when Ball first saw her future husband Desi Arnaz.
Ironically, in later years, star Lucille Ball would actually own RKO, the company that made this film.
This film is included in the book "1001 Movies You Need to See Before You Die", edited by Steven Jay Schneider.
