Lou Costello's father, a Western film buff, died during the production of this movie, and as a tribute Lou listed him in the credits as Associate Producer Sebastian Cristillo.
The story was based on a law in effect in Montana in the 1880s, which stated that a man who killed another man was responsible for the care and support of his victim's family.
The film was originally written for James Stewart, but when he couldn't commit to it, it was re-fashioned for Bud Abbott and Lou Costello, with Costello playing the part intended for Stewart.
Patricia Alphin was originally cast as Juanita, but two weeks into shooting she was hospitalized with a burst appendix. She was replaced by Audrey Young.
