Sorry Larry, catching up here ... Just read your question:
Isn't it "based on a true story?"
Do you mean the political situation in The Year Of Living Dangerously
? Yes, it certainly was! Resulted in a purge of Sukarno's supporters - a bloodbath of mammoth proportions. This by the way, was supported by the CIA, who saw Sukarno as dangerous (Communist sympathies).
The film revolved around a group of international journalists, covering the last months & days before the fall of Sukarno. This period became known as "the year of living dangerously" in Indonesea.
Well worth a look, if you get the chance. Rivetting!
