John Boorman has stated that the myth of King Arthur informs his filmography, and that’s not hard to see in The Emerald Forest, scripted by the same Rospo Pallenberg who wrote Boorman’s Excalibur. As with Arthur, a special boy (director’s son Charley Boorman in a striking performance) has the magical power to lead his people. Instead of drawing a sword from a stone, he draws stones from a river and ends up going on a quest to a strange, forbidding land. That land is what most of us call “civilization”, and it’s a savage place, as represented by a modern city on the Amazon. The boy’s quest is the inversion of the quest by his father (Powers Boothe) through the jungle in search of his son, so the movie gives us two quests and two irreconcilable viewpoints for the price of one.
