The title of Dig Two Graves comes reportedly from the writings of Chinese philosopher Confucius, who emphasized the cultivation of character virtues and wisdom above action. It’s debatable whether or not he’s actually responsible for the phrase, which essentially is a warning to those seeking vengeance. Of the two graves, one is for the quarry, but the other is, metaphorically, for the death of the soul of person seeking that vengenance. In effect, it’s saying that the cost of vengeance on those seeking it is greater than the sense of justice one expects to come from achieving it. Upon watching the movie, I mostly disagree with using the phrase as the title.
