Errol Morris on Donald Rumsfeld: 'One of the strangest interviews I've ever done' Documentary maker Errol Morris's latest film, The Unknown Known, is a series of interviews with former US defence secretary Donald Rumsfeld. As the film is released in UK cinemas, Morris tells the Guardian's Andrew Pulver about Rumsfeld's famous smile and what it's like coming face-to-face with one of the principle architects of America's War on Terror.
