Like its immediate predecessor, ''Tarzan Triumphs'', the film makes reference to Tarzan's mate, Jane, played in earlier Weissmuller films by Maureen O'Sullivan, but it does not show her on screen. The explanation given is that she is in England helping the war effort. (When the character of Jane finally did return in the next Tarzan film, she was played by Brenda Joyce (actress), not O'Sullivan.)
