Maureen Sullivan is back as Jane in the second Tarzan movie, this time showing lots of skin in a little loincloth outfit that probably drove my grandfathers crazy. (Her daughter Mia Farrow is another Hollywood beauty.) The movie censorship code was in effect but not widely enforced at the time this movie was made. These pre-code Tarzan movies are more than simple jungle adventure stories for children. They're really as much about sex and romance - about Jane and the lust she inspired in Tarzan and half the audience, and the nearly-naked knife-weilding elephant-talking Johnny Weissmuller's effect on the other half.
The first crocodile scene in this movie begins with Jane swimming in a pond when a crocodile comes after her. She gets to roll around with a big rubber fake crocodile that does nothing but spin around when it could have easily made a meal of her if it bothered to use its jaws. She makes the Tarzan call and Tarzan calls back to her running up and jumping in the water with his knife. He fights the croc underwater for what seems like an hour, then finally kills it.
Cheetah the chimp even gets a crocodile scene - chased by a lion, he jumps on a log and paddles out into a pond when a crocodile comes after him but he gets to the shore in time to jump onto the land and run away.
