Duel is a 1971 television (and later full-length theatrical) thriller film directed by Steven Spielberg and written by Richard Matheson. It stars Dennis Weaver as a terrified motorist stalked on a remote and lonely road by the mostly unseen driver of a mysterious tanker truck. The script is adapted by Richard Matheson from his own short story, originally published in Playboy magazine. It was inspired by a real-life experience in which Matheson was tailgated by a trucker while on his way home from a golfing match with friend Jerry Sohl on November 22, 1963, the same day as the John F. Kennedy assassination. The short story was given to Spielberg by his secretary, who reportedly read the magazine for the stories. The film received many positive reviews and is often considered among the greatest TV movies.
