According to Robert Taylor's biographers, his mother walked out in the middle of this movie, upset by all the punishment her son was apparently receiving during the boxing scenes. She asked her son why stand-ins couldn't have been used.
Victor Fleming directed two retake scenes in July 1938 because Richard Thorpe already had been assigned to direct another production.
