At the time of filming, all five of the leading male players, Carey, Gibson, Williams, Steele and Tyler, were all enjoying name-above-the-title status in their own own series of Westerns at various independent studios.
Though not the main leads in this precursor of The Three Mesquiteers series of westerns, Bob Steele and Tom Tyler paired up as members of The Three Mesquiteers in 13 later movies.
This filming of the William Colt MacDonald novel would lead to the popular The Three Mesquiteers series which was based on the same three main characters in this film.
Neither Hoot Gibson nor Guinn Willams wears a holster; both carry their guns stuck into their pants. This was the norm for Gibson, who often didn't wear a gun at all in his westerns.
The plot device of the gunfighter hired to kill the hero but eventually takes the hero's side was later used in the George O'Brien film "Marshall of Mesa City", with O'Brien as the hero and Henry Brandon as the gunslinger.
