Columbia's B pictures were generally the worst of the major studios. It's hard to forgive them for those awful Jungle Jim films and producer Sam Katzman generally had no artistic quality in his product. Maybe his absence explains the relative excellence of the Whistler series, in particular this very early entry in the Psycho Killer stakes. More reminiscent of Val Lewton than Katzman, The Power of the Whistler foreshadowed many Hollywood psychological features of the next half century.
