||In the late 1970s director Francis Ford Coppola began filming his monumental Vietnam epic, APOCALYPSE NOW. Shot in the Philippines, the film would eventually take years to complete and include 238 days of principal photography, the lead actor's firing, the replacement star's heart attack, a typhoon on the set, difficulties with an overweight Marlon Brando, ritualistic animal slaughter, and President Marcos' war with rebels. Coppola's wife, Eleanor, documented his struggles during the marathon moviemaking by using her own film crew to shoot behind the scenes and secretly tape conversations with her tormented husband. Her work was used by filmmakers Fax Bahr and George Hickenlooper for their riveting documentary HEARTS OF DARKNESS. Using interviews with the stars of the film, including Martin Sheen, Robert Duvall, Frederic Forrest, and Dennis Hopper, the producers and production crew, and especially Coppola himself, the filmmakers unravel the story behind the making of APOCALYPSE NOW and the director's torturous search for an ending. Coppola compared his film to America's efforts in Vietnam: "We were in the jungle, there were too many of us, we had access to too much money, too much equipment, and little by little we went insane."
