Fury of the Congo was the sixth entry in Columbia's "Jungle Jim" series, though in most markets it was the fifth to be released. Johnny Weissmuller returns as Alex Raymond's comic strip hero Jungle Jim. The plot this time around has Jim coming to the rescue of a native tribe which has fallen under the influence of evil dope peddlers. Benumbed by drugs, the tribesmen have been ordered to hunt the Okongo, a hybrid beast that is the source of a dangerously powerful narcotic. The film builds steadily to an exciting climax in a blinding sandstorm. The villainy is handled by William Henry, Lyle Talbot and George Eldredge, while the "femme interest" is provided by shapely native girl Sherry Moreland.
