Hearts of Darkness: A Filmmaker's Apocalypse (1991) is an award-winning documentary about the making of the film Apocalypse Now. The title is derived from the source material for Apocalypse Now, the Joseph Conrad novella Heart of Darkness. Using behind the scenes footage, and narrated by Eleanor Coppola, it chronicles how production problems including bad weather, actors' health and other issues delayed the film, increasing costs and nearly destroying the life and career of Francis Ford Coppola. In 1990, Eleanor Coppola turned her material over to two young filmmakers George Hickenlooper and Fax Bahr who then shot new interviews with the original cast and crew and intercut them with her existing material. After a year of editing, Hickenlooper, Bahr, and Coppola debuted their film at the Cannes International Film Festival to universal critical acclaim.
