The working title of this film was Thundering Trail. The Black Lash begins with a voice-over narration recounting how the West grew more wild in the late 1800s, and dedicating the film to the memory of heroes such as Bat Masterson and Wild Bill Hickok. The Black Lash includes some footage from the 1948 Western Adventure Productions film Frontier Revenge, and the two films share similar plotlines (see AFI Catalog of Feature Films, 1941-50). Although Timothy Ormond and June Carr are listed as screenwriters in the opening credits, contemporary reviews and modern sources credit the screenplay to Kathy McKeel, a pseudonym of June Carr. Modern sources add the following actors to the cast: Lee Roberts, Jim Bannon, Lee Morgan and Sarah Padden.
