Lesser's first RKO Tarzan film had made the Ape Man a symbol of American isolationism. The film was the highest grossing of Lesser's Tarzan films. Unlike in previous Tarzan films, the natives are played by whites in South Sea Island costume rather than the black Africans of the MGM films. This use of non-blacks as natives continued for several other Tarzan films in the 1940s. Reception The film made a profit of $208,000.
