The Disenchanted Forest is a 1999 documentary film that follows endangered orphan orangutans on the island of Borneo as they are rehabilitated and returned to their rainforest home.

It centres on the three main Borneo Orangutan Survival Foundation (BOS) projects - Wanariset, Nyaru Menteng and Mawas.

[1][2] In the Bornean rainforest Dr. Anne Russon, primate psychologist, broaches new territory in the attempt to understand orangutan intelligence and psychology.

The destruction of the orangutan's habitat to make way for palm oil plantations and the illegal pet-trade threaten the lives of these great apes.

Dr Carl Van Schaik, primatologist, discusses the rapidly diminishing opportunity to learn about human evolution as the number of wild orangutans dwindles precariously.
