I remember a fragment of a British war film, it's set in the far east and there's a portion where a Japanese soldier is taken prisoner and one of the Brits figures he can make himself understood to the Asian if he speaks English with an extremely faked up Japanese accent. I don't remember it well enough to know if it was made plain in the movie whether the Brit was dumb enough to think this should work, or employing his own bit of psychological mischief. I found it to be a disturbing insight into how people think, how people communicate, and how people think they communicate.
