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.
Lee 'Lasses' White, who appears in the opening scene as the stagecoach shotgun rider, was dubbed in the film by Billy House, who appeared the same year in Universal's The Egg and I.
The film was originally written for James Stewart, but when he couldn't commit to it, it was refashioned for Bud Abbott and Lou Costello, with Costello playing the part intended for Stewart.
The story was based on an actual 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.
