We meet Betty and her father William indulging in the upper-class joy of watching a yacht regatta when her fiancé Bruce announces that he and his buddy Andy are soon heading to Africa in search of the lost City of the Dead. Betty wants to go along for the excitement and, as her father's brother James is a missionary over there, they both decide to go. In Africa (after a few minutes of stock footage of hippos and crocodiles and snakes and zebras) we see Father James conferring with Bob, a research doctor who is on the verge of finding a cure for the dreaded malaka fever. When our American visitors arrive, Betty is nearly attacked by a leopard which Andy shoots, and a little later, Bob saves her from a lion. (Despite Betty coming off as strong-willed, she spends most of the movie screaming for someone to save her.) James is happy to see his brother and niece, and Betty seems happy to make the acquaintance of the handsome Bob, something which triggers a bit of jealousy in Bruce. Rounding out the group are Buck, the nervous nelly comic relief, and James' pet tiger Satan. After Bruce and Andy set out for the lost city, Bob gets news that a shipment of his fever cure has gone down with a sunken ship off the coast, just as an attack has broken out in a nearby village. He and Betty go to the village to tend to the sick as Bruce finds the lost city and snaps lots of photographs. When Bruce and Andy return to the village, Bruce has malaka fever, so Bob decides to head to the coast to try and salvage the sunken serum. He does, but on his return, Betty has the fever as well. Can Bob save them?
One of the things I liked about this and that separates it from the average jungle melodrama of the era is that there is no villain, no bad guy actively trying to sabotage either the city seekers or the doctor. Also, despite the title, there is no real Tarzan figure, though there is a former Tarzan actor, the hunky and stoic Buster Crabbe, as Bob (pictured) who, while never donning a loincloth manages to get shirtless a couple of times. It was fun to see him co-starring with Charles Middleton as Father James; their previous work together was as good guy Flash Gordon and bad guy Ming the Merciless in the Flash Gordon serials—and Middleton is passive and laconic here, looking nothing at all like Ming. Sheila Darcy makes for a colorless Betty, just as she made a colorless Dragon Lady in the Terry and the Pirates serial. For the record, Weldon Heyburn and Robert Carson are OK as Bruce and Andy, though Vince Barnett has the sadly thankless part of Buck who meets an unhappy end, rare for comic relief characters. I liked seeing the City of the Dead, which was actually the real life Angkor Wat temple in Cambodia. Other viewers have noted that it feels like stock footage fills up almost half of the movie's one hour running time, but such footage is par for the course for a B-adventure film of the time. Best exchange: Bob, as he prepares to give Betty the serum, "You’re my first guinea pig"; Betty, "It's nice being your guinea pig." I liked this, but it's pretty much for die-hard B-jungle film fans (or Buster Crabbe fans) only. [YouTube]
