Forty-eight years ago, on Nov. 22, 1963, President John F. Kennedy was assassinated in Dallas, Texas, sparking a wrath of conspiracy theories that live on to this day. The Kennedy assassination has been explored by everyone from Oliver Stone to Zack Snyder to Stephen King, and now Oscar-winning documentarian Errol Morris has taken a look at the national tragedy for the New York Times -- though not how you might think. "For years, I've wanted to make a movie about the John F. Kennedy assassination," Morris wrote in the Times. "Not because I thought I could prove that it was a conspiracy, or that I could prove it was a lone gunman, but because I believe that by looking at the assassination, we can learn a lot about the nature of investigation and evidence." The result? Morris's new fascinating short film, 'The Umbrella Man.'
