The real reason to see this jungle exotica classic is Claudette Colbert's transformation from a prim and proper geography teacher in glasses to a sexy a jungle girl in a leopard print bikini(!?) (the timid teacher attempts to dry out some guy's shoes by a fire and ends up burning them up. He get's pissed but she was just trying to help, so she runs off into the jungle mad and in tears...and then starts to get some backbone after standing up to snakes and alligators...YOWZA!!)
Watching this made me think this could have been the original blueprint for Gilligan's Island. There's a professor and a Mrs. Howell type the running gag is she always carries this little dog with her that they must have heavily sedated for the role. They trade the old bag for a new bag of rice so they can pass through some forbidden territory, so she stays and tries to reform the natives and tried to teach them about planned parenthood (!?) Even when she's teaching native kids how to chuck spears she's still holding this little chihuahua or something and lecturing the primitives not to have so many babies. Much less melodramatic, corny and sentimental than most stuff from that era and a LOT more interesting. From Cecil B. De Mille (you may have heard of him.)
