 The document that Willard skims through near the films conclusion,  on which "DROP THE BOMB. EXTERMINATE THEM ALL" is scrawled, is  entitled "The Role of Democratic Force in the Underdeveloped World,  by Walter E. Kurtz, Colonel USSF" and is "Commissioned by The Center  For Democratic Studies, Santa Barbara, California". This is taken  directly from Joseph Conrad (I) (qv)s novella, where a report  written for "the International Society for the Suppression of Savage  Customs" by Kurtz is also graffitied with a similar message:  "Exterminate all the brutes!"
