I don't wish to see the trailer but were the Afghan guy's comments in subtitles & if so, how do we really know he said it? I just want to be careful not to fall for propaganda or whatever.
If he's shown blatantly speaking English, however, I'll trust that he said it.
I asked one of my old army buddies who is Afghan, and he says the only thing wrong with the subtitles is that there is no word for fuck.
