Mowgli looks about 10 years old. His wolf brothers would be mature adults by this time, but are still depicted as youths, and the parent wolves and Akela are still alive when they would have died of old age.
Just as in the Disney remake, the name Akela is incorrectly pronounced "ah-KEE-la" in this film. The correct pronunciation is "ah-KAY-la" (it's an Indian word meaning "alone").
The elephants don't look like Indian elephants. They look like African elephants.
