The Unspeakable Secret
I love this movie, it is dark and tragic and brutally defies the conventional pieties about heroes and competition. I also find that with repeated viewings a dark Oedipal mystery unfolds. First Cobb claims his mother mistakenly shot his father when he was sneaking around the house checking up on her. Then Cobb admits that his mother really was cheating and that it was actually her young lover who shot his father.
What I want to know is -- did anyone else get the impression that Cobb hints that it was he himself who shot his father? And that he had committed incest with his mother? There are hints all through the film but nothing concrete. Cobb stresses that his mother was only twelve when she married his father, that she was "the most beautiful woman in the county." He also implies that his father was a fanatical Christian who neglected his wife and was away much of the time. When he describes the aftermath of the killing he says "a man should defend his mother at all times." Ostensibly he is referring to her trial, but might he not be hinting that he was the one who shot his father? And that he did so to prevent detection in the act of incest? It seems not much of a stretch to imagine that Cobb's unspeakable secret is that he has committed the ultimate sin and gotten away with it.
