Eighty years after Conrad’s novella debuted, the Francis Ford Coppola film Apocalypse Now hit the big screen. Though heavily influenced by Heart of Darkness, the movie’s setting is not Belgian Congo, but the Vietnam War, and though the antagonist (played by Marlon Brando) is named Kurtz, this particular Kurtz is no ivory trader, but a U.S. military officer who has become mentally unhinged.
