Factual error: Near the end of the movie, Raul is telling the hunter to not kill the tigers. Throughout the scene, you can hear a bird call. The bird is a grebe. Grebes do not live in the jungle- they are only found near large bodies of water.
Continuity mistake: In the scene where the hunters trap Saunga and his mother in a pit, they put a bamboo cover on top. Then, when the cover is lowered to begin the tiger hunt, the mother goes AROUND the side of the cover. How could it have fit in like this, with enough room for a full-grown tiger to walk around it?
Continuity mistake: At the beginning of the film, both of the tiger cubs have brown eyes. When the hunter has captured Kumal, there is a close up of the tiger cub sucking on a bottle. Its eyes are blue. After this, Kumal's eyes are brown again.
