Brooding, raw, honest, he was unlike anyone audiences had seen before. Now the mark of his style is in descendants from De Niro to DiCaprio.
柯波拉另外一齣改編自康拉德（Joseph Conrad）小說《黑暗之心》（Heart of Darkness）的史詩電影現代啟示錄，仍由馬龍白蘭度飾演要角柯茲上校：
美國越戰期間，維樂上尉（馬丁辛 飾）被派遣出任一項特別任務，他奉命率領數位軍人沿河而上，深入柬埔寨內地找尋並秘密暗殺精神已達瘋狂狀態、濫殺無辜的柯茲上校（馬龍白蘭度 飾）。但沒想到旅途上的種種灰暗面，讓這一群人的心智也慢慢的改變…。
柯茲上校最後是沒有反抗地讓維樂上尉砍頭，死前他喃喃說道 : "The horror, the horror."
他認為訓練出不會懼怕的部隊，就可以打贏越戰，所以必須要佔領山頭從事訓練任務。（但是政府認為他瘋了！） 原文如下 :
Kurtz: I've seen the horror. Horrors that you've seen. But you have no right to call me a murderer. You have no right to call me a murderer. You have a right to kill me. You have a right to do that, but you have no right to judge me . It's impossible for words to describe what is necessary to those who do not know what horror means. Horror. Horror has a face, and you must make a friend of horror. Horror and mortal terror are your friends. If they are not, then they are enemies to be feared. They are truly enemies.
I remember when I was with Special Forces--it seems a thousand centuries ago--we went into a camp to inoculate it. The children. We left the camp after we had inoculated the children for polio, and this old man came running after us, and he was crying. He couldn't see. We went there, and they had come and hacked off every inoculated arm. There they were in a pile--a pile of little arms. And I remember...I...I...I cried, I wept like some grandmother. I wanted to tear my teeth out, I didn't know what I wanted to do. And I want to remember it, I never want to forget. And then I realized--like I was shot...like I was shot with a diamond...a diamond bullet right through my forehead. And I thought, "My God, the genius of that, the genius, the will to do that." Perfect, genuine, complete, crystalline, pure. And then I realized they could stand that--these were not monsters, these were men, trained cadres, these men who fought with their hearts, who have families, who have children, who are filled with love--that they had this strength, the strength to do that. If I had ten divisions of those men, then our troubles here would be over very quickly. You have to have men who are moral and at the same time were able to utilize their primordial instincts to kill without feeling, without passion, without judgment--without judgment. Because it's judgment that defeats us.
