This is the first of at least two Tarzan features that Sol Lesser will turn out for RKO release, after Metro wound up its interest in the jungleman’s adventures last fall [with Tarzan’s New York Adventure].
Virtually all jungle stuff, Tarzan Triumphs [from a screen story by Carroll Young] has good portion of stock animal shots and includes a hidden city for convenient takeover by a squad of Nazi paratroops and subsequent battle in which Tarzan, with the aid of the subjugated natives, knocks off the invaders and restores peace in the jungle territory.
Usual tree-swinging, dashes through the jungle undergrowth, and other familiar Tarzanian ingredients are again on display. Also boy (little Johnny Sheffield), the chimp Cheta and the small elephant. Inability to obtain Maureen O’Sullivan for this picture switches script for her to be visiting in England, with Frances Gifford filling in as the girl from the hidden city.
Weissmuller and Sheffield run around as usual without necessity of displaying much acting ability. Direction by William Thiele hits usual standard for the Tarzan features.
