The Lost City is an independently made science fiction film serial created and produced in 1935 by Sherman S. Krellberg and directed by Harry Revier.

Plot
Scientist Bruce Gordon comes to a secluded area in Africa after concluding that a series of electrically induced natural disasters had originated from in the area. There he finds the crazed Zolok, last of the Lemurians, in a secret complex inside a mountain. Zolok had created the natural disasters as a prelude to his attempt to take over the world, holding a brilliant scientist, Dr. Manyus, there hostage, along with his daughter, Natcha. He had forced Manyus to create mindless “giant” slaves out of the natives as a private army and as the serial progresses we learn Manyus also turned another tribe, the spider-worshipping Wangas, into thin, impotent whites. Gordon helps Manyus and his daughter to escape Zolok, but they encounter Ben Ali, a malignant slave trader; meet the sexy native Queen Rama, who tries to help them; and survive harrowing jungle adventures before returning to the Lost City and stopping Zolok’s plan.
