This was William Witney's first time working on a serial, although not as director (that would be "The Painted Stallion" in 1937). In "The Vigilantes Are Coming" he worked as a second unit director and as an extra (a Cossack). It was the only serial Republic produced in this year, 1936 (the first year of serial production for Republic), where the lead character did not share the name of the lead actor (although "Crash" Corrigan in the previous Republic serial, "Undersea Kingdom", had his stage name created specifically for that serial).
