Lord of the Jungle (1999)

The film starts off with a woman and a baby on a plane. The plane, for no apparent reason, fails and crashes into a jungle. The baby survives and is adopted and brought home by a gorilla named Shina. She brings him to her troop, where he is ridiculed for being different from the rest of them. The yet to be named baby is allowed to stay on the condition that he is to go if he causes any trouble. Shina names him Lord and he quickly adjusts to life as a gorilla.
