Sure. 'Jungle' is a great jungle film based on a true story. It shows the harrowing survival story of Yossi Ghinsberg in the Amazon rainforest. He got lost in the jungle and had to face many difficulties like starvation, dangerous animals, and the unforgiving environment.
There's also 'Apocalypto'. While it's a fictionalized account set in a pre - Columbian Mayan civilization, it was inspired by true aspects of that culture and the jungles they inhabited. The film is intense, with great visuals of the jungle and the brutal way of life at that time.
One such film is 'Aguirre, the Wrath of God'. It tells the true - ish story of a Spanish conquistador's journey into the Amazon jungle. The film shows the harsh conditions and the slow descent into madness. Another is 'The Emerald Forest'. It's based on a true story about a boy who was abducted by an indigenous tribe in the Amazon and his father's search for him.
