In the 1940s, director Sam Fuller dove deep into the jungles of the Amazon to film what he hoped would become a John Wayne classic. There, he got to know the Karaja Indians, who generously allowed him to make his movie in their community. Joined by groundbreaking helmers Jim Jarmusch and director Mika Kaurismaki, Fuller relives the challenges he faced during that time and ruminates on his life as a filmmaker.
