There was a serial and movie of this released at the same time. They filmed several principal scenes with different dialog along with a new ending to make two totally different films. It’s also sort of a sequel to another serial, Darkest Africa.

This stars Clyde Beatty, who was one of the most famous circus performers and animal trainers in the world. He got into the business by hitching a ride on a train and joining Howe’s Great London and Van Amburgh’s Wild Animal Circus. His greatest shows had him in a cage alone with 43 lions at the same time. His wife Harriett Evans and his daughter Albnina were both animal trainers.

Directed by David Howard (Mystery Ranch) and Armand Schaefer (who went into producing when TV came around), who wrote the story with Wyndham Gittens and Barney A. Sarecky, this has Clyde looking for his lady Ruth (Cecilia Parker) in the jungle. He even crashes a zeppelin to get out there! Every animal is real except for the guy in the ape suit.
