Though inspired by Joseph Conrad’s classic tale Heart of Darkness, Francis Coppola’s Apocalypse Now is the kind of film we don’t ordinarily think of as an adaptation. And not simply because of its change of tide. It doesn’t acknowledge its literary source in its credits—they simply read: “Screenplay by John Milius and Francis Coppola; Narration by Michael Herr.”
In The Power of Adaptation in "Apocalypse Now" Marsha Kinder critically compares and contrasts the film and the novel. In this article, Kinder states that "Coppola rarely hesitates to change Conrad's story-setting, events, characters-whenever the revision is required by the Vietnam context."
What does Apocalypse Now mean—the film as we have it, considering the minimal difference between the 35mm version with the title sequence and the 70mm version without, but ignoring all the prerelease stories and versions, preliminary scripts, and encrusted commentary?
