At the end of the film when Pran and Sydney meet each other again at the refugee camp, the two men hug while "Imagine" plays in the background. It seem heartwarming at first, however, if you actually look at the song's lyrics, a lot of the ideas that Lennon advocated for in his song was exactly what the Khmer Rouge seek to achieve. E.g. "no religion", "no possessions", "a brotherhood of man", "all the people sharing all the world", etc. Was it meant to be ironic and show the viewers how even noble ideas can be corrupted, or was it meant to show how the western liberals were ignorant in advocating for that kind of society?
