This quest didn't take long as by the next film in the series Nevada Jack McKenzie was a full-fledged U. S. Marshal.

Set on the Mexican border in 1850, Bad Men of the Border was the first of seven Universal Westerns starring handsome Kirby Grant, a former singer from Montana who had earlier acted under the name Robert Stanton. The series, Universal's last attempt at competing with Republic Pictures' many streamlined B-Westerns, also featured the bucolic Fuzzy Knight as Grant's sidekick.
