In the course of filming the 1979 cinematic classic "Apocalypse Now," Francis Ford Coppola pushed his cast and crew to such extremes that his star Martin Sheen ended up having a heart attack and a breakdown.
A dozen years passed before most of the public heard about that or the rest of the behind-the-scenes mess that plagued "Apocalypse Now." It officially became public via "Hearts of Darkness: A Filmmaker's Apocalypse," a documentary co-directed and narrated by Coppola's wife Eleanor using the copious footage she took of the production.
