One of the great writers for “The Twilight Zone,” Richard Matheson, passed away this year. As we observe that fateful date in Dallas, November 22, 1963, I think of how one man created art out of the processing of his emotions from that event. You might find this to be a surprise but “Duel,” the short story about a man fighting for his life against a demonic semi-trailer truck, that went on to become Steven Spielberg’s first major movie, has its origins in the Kennedy assassination. It’s not a direct link. It’s more based on a significantly deep dark feeling of despair and dread.
