The first movie version of "The Quiet American" was made in 1958. However the story was changed to suit American propaganda purposes - with input from the CIA via Edward Lansdale (read "The Unquiet American" by Curry.
Another example of American efforts to cover up their murderous and illegal activities in Vietnam.
Finally this re-make tells what Graham Greene wanted to say - that as far back as the 1950's, America was gearing up for war - and just looking for excuses to wage it - as it continues to do now. CIA operatives hide under the title of "Technicians" "Doctors" "Advisors" and so on. Really murderers and criminals who should be imprisoned, or hanged.
Greene would be happy to know that finally his book has been truthfully made into a movie. He tried to warn, and maybe prevent the American War in Vietnam. Yet American aggression was too strong, and an unnecessary war was waged on a poor and underdeveloped country, under the "Bright Shining Lie" of trying to "save" Vietnam from "falling". Yet all Vietnam and Ho Chi Minh wanted was independence from foreigners - unacceptable to the US - "wars of national liberation cannot be supported".
See this movie and reflect on what America has done to the world since the end of World War 2. It has taken the methods and madness of Nazi Germany and spread unrest, destruction, murder and war around the world. And it has failed to show any remorse for it's immoral and illegal actions.
With regard to the American War in Vietnam, the US should be forced to pay the reparations it promised Vietnam - $3.5 billion - in todays terms about $15bn - and it should be forced to admit it's guilt, and assist Vietnam in cleaning up the millions of unexploded bombs and mines still killing innocent people today.

The message of the Quiet American is to never trust the US, never believe it, and keep the evil virus out of your country, if you can! "The Quiet American" is a message that arrived too late for Vietnam, but perhaps not for other countries.
