Popular latter-day serial queen Linda Stirling starred in the title role in this well-made 12 chapter serial produced by genre specialist Republic Pictures. Stirling plays Barbara Mededith, a pretty girl who takes over her murdered brother's crusading newspaper. She also assumes the dead sibling's identity as "The Black Whip," righting the wrongs of Crescent City very much in the manner of her famous ancestor, Zorro. Off course, "being a mere woman," Barbara needs the assistance of a stalwart young man, in this case Vic Gordon (George J. Lewis), a government secret agent. Arguably the most popular serial heroine since the days of Pearl White, Linda Stirling's other top-billed serial role was as The Tiger Woman (1944). The choice of Lewis as Stirling's male lead was surprising; the Mexican-born Lewis, although handsome enough and a veteran of Universal's popular "Collegians" 2-reelers, had recently played mostly villains. Produced by Ronald Davidson, Zorro's Black Whip benefitted from second unit direction by stunt-man extraordinaire Yakima Canutt and special effects by the famed Theodore Lydecker.
