This Italian Tarzan picture has been ignored by most chroniclers of the Ape Man's screen career. Perhaps this forgotten film, originally titled Tarzan Contra los Hombres Leopardo, was produced without authorization from the Burroughs estate. Whatever the case, Ralph Hudson plays the "Lord of the Jungle", who comes to the aid of a scientific expedition. In the course of many adventures, Hudson does battle with the dreaded Leopard Men. John Chevron and Nuccia Cardinali costar in this uneven actioner.
