First Tarzan film to be shot in Africa, where it was set.
The company arrived in Africa just before winter set in. The chimps wouldn't perform, so Cheetah's part had to be cut. The area around Mount Kenya was so cloudy that Lex Barker's tan disappeared and he had to use body makeup. The first time Barker showed up in a loin cloth the native extras burst out laughing.
The film was originally shot in color, but more than half of it was ruined on location. It was converted to black and white, the remaining footage winding up in later pictures.
