The title King of the Bullwhip could only refer to one of two western-movie favorites: Lash LaRue or Whip Wilson. Since LaRue was under contract to Ron Ormond productions, it was LaRue who starred herein. Usually associated with the lowest of low-budget productions, LaRue is here surrounded with decent production values and an above-average cast, including Jack Holt, Anne Gwynne, Tom Neal, Michael Whalen, Dennis Moore and George Lewis. And, as always, LaRue is aided and abetted by trusty comical sidekick Al "Fuzzy" St. John. Likewise praiseworthy is the plot, a solid mystery yarn concerning an unknown bank robber. The finale finds LaRue subduing the villain with a startling exhibition of expert whip-cracking.
