Francis Ford Coppola's Vietnam War epic, starring Martin Sheen, Marlon Brando and Dennis Hopper, was a modern adaptation of Joseph Conrad's novella Heart of Darkness. The film became notorious in the entertainment press due to its lengthy and troubled production, as documented in Hearts of Darkness: A Filmmaker's Apocalypse. Marlon Brando showed up to the set overweight and Martin Sheen suffered a heart attack. The production was also beset by extreme weather that destroyed several expensive sets. In addition, the release date of the film was delayed several times as Coppola struggled to come up with an ending and to edit the thousands of feet of footage that he had shot.
