Apocalypse Now is a 1979 American epic war film directed, produced, and co-written by Francis Ford Coppola. It was co-written by John Milius with narration written by Michael Herr. It stars Marlon Brando, Robert Duvall, Martin Sheen, Frederic Forrest, Albert Hall, Sam Bottoms, Laurence Fishburne, and Dennis Hopper. The screenplay, written by Milius, adapts the story of Joseph Conrad's novella Heart of Darkness, changing its setting from late nineteenth-century Congo to the Vietnam War ca. late 1960s–early 1970s. It draws from Herr's 1977 Dispatches and Werner Herzog's Aguirre, the Wrath of God (1972). The film revolves around Captain Benjamin L. Willard (Sheen), who is on a secret mission to assassinate Colonel Kurtz, a renegade Army officer who is presumed insane.
