spoiler alert -- is the story of those 76 men true?
I don't know for sure this is a spoiler, but it does happen late in the movie, so be warned....
Is the story of the 76 prisoners, who chose not to return to either side, true?
I think it is true.
I remember watching a documentary about one of the POW who went to South America. He was so traumatized that he could barely speak in Korean even though he got there in his 20s...
