Universal's 19th sound-era serial (between "The Phantom of the Air" and "Perils of Pauline") and Buck Jones' first serial was an extended remake of Universal's 1932 "Flaming Guns" starring Tom Mix. Craig Reynolds (billed as Hugh Enfield and playing Ed Roberts) was not billed 4th in the cast as some source seems to think, but he was billed 2nd (to Evalyn Knapp) in Universal's next serial "Perils of Pauline" but under the screen-billing name of Robert Allen. That name, Robert Allen,appeared often in many films, with the most use belonging to Columbia contractee and western star Robert Allen.But, aside from him and Craig Reynolds'use of it in "The Perils of Pauline', it also appeared in the cast listing for three or more westerns produced/directed by Robert Emmett Tansey in the 1940's, and the players actually playing the role attributed to "Robert Allen" in the cast listing turned out to be director/actor Robert F.Hill once, John Tansey once and Lee Roberts once.
