Typical Tarzan stuff with lost city, lion pit, machetes in the jungle, etc. However, this gets 4 stars for the performance of Denise Darcel as the French firecracker nurse Lola who steals the movie away from Tarzan, Jane, and the tiresome Cheeta. Darcel looks like she could beat up everyone in the film, Lex Barker's Tarzan included. She has a real French accent thicker than Pepe Le Pew, and always speaks her mind, even telling Jane she better keep an eye on Tarzan when Lola is around. She also get points for being the only pre-1970s woman to do anything useful in a fight with a man in a movie. Looking Darcel up on the IMDB, I see that supposedly she rejected the advances of Howard Hughes and Columbia Pictures head Harry Cohn, and that was that. She ended up as a card dealer in Vegas.
