The Emerald Forest
John Boorman's 1985 South American epic never quite gets all of its gears working simultaneously, but it remains an often startling work with an extraordinary performance by the director's own son, Charley Boorman. Powers Boothe plays an American engineer working on a dam project in Brazil. When his young son is seemingly absorbed one day into the dense perils and beauty of the Amazon rain forest, Boothe's character goes on a protracted, 10-year search for him.
