"Tarzan with clothes on". That's how one reviewer summed up Sam Katzman's newest film series Jungle Jim, starring ex-Tarzan Johnny Weissmuller in the title role. Based on the popular comic strip by Alex Raymond (previously cinematized as a 12-episode Universal serial in 1936), this first entry in the "Jim" series finds our hero guiding gorgeous lady scientist Hilary Parker (Virginia Grey) through the wilds of Africa-actually the Columbia back lot and nearby Bronson Canyon-in search of an herb that will cure infantile paralysis. At first, Hilary resents Jungle Jim's casual chauvinism, but after being nearly killed on several occasions (she apparently can't take two steps without confronting a lion or snake) she's willing to acknowledge his expertise in all things African. Once Hilary's expedition has arrived in a hidden native village, they find themselves as the mercy of crooked gold prospector Bruce Edwards (a pre-Superman George Reeves), who foments a tribal sacrifice as a means of putting the good guys out of the way. Many of the film's wildlife scenes were culled from the 1930 documentary Africa Speaks, which continued to be cannibalized throughout the subsequent 15 "Jungle Jim" epics.
