I think this was Sabu's first movie, he was about thirteen when it was made. This is a  black and white movie based on Rudyard Kipling's "Toomai, of the Elephants". Sabu plays Toomai, the son of an elephant trainer. Toomai and his father have the largest, gentlest elephant around, an elephant which had been passed down to Toomai's father from Toomai's great grandfather. But Toomai, like many boys of his age in India at the time, dreams of being a hunter. When a white hunter comes to find elephants to use in hunting wild elephants (this is long before the general public worried about preserving elephants), Toomai's father takes Toomai's elephant for employment, and Toomai goes with him. When the white hunter learns that Toomai's mother is dead and he must stay by himself when his father is away on a hunt, he offers to let the boy come along. After about six weeks of hunting they still have not found any sign of wild elephants, if they do not find some soon they will have to go back empty handed. Then tragedy strikes, a tiger comes into camp and Toomai's father is killed. Toomai is to be sent back to the village, and his elephant is to be left with a trainer who treats his elephant's harshly. Toomai's elephant, used to being treated kindly, and upset by the lose of his trainer, revolts and injures the new trainer. Toomai, afraid that his elephant will be put to death for injuring the man, runs off into the jungle with his elephant. There he finds a great herd of wild elephants and sees them dance (watch the movie and you will understand that commit). When the hunters catch up with Toomai he tells what he saw and lead the hunters to the elephants, saving the hunt. Toomai is told his elephant is not to be put to death for what he did, and it is also decided that Toomai is to be trained as a hunter because seeing the elephants dance must be a sign that he was born to be a hunter.
 There are, by the way, a number of good wildlife shots in this movie.
