Directed by Mel Stuart, the documentary "Four Days in November" explores the assassination of John F. Kennedy and its impact through a variety of sources -- from professional media coverage to amateur footage, as well as re-enactments of the crime. Events surrounding the assassination also are included in the documentary, such as the swearing in of Vice President Lyndon B. Johnson on Air Force One and Jack Ruby's shooting of the suspected assassin, Lee Harvey Oswald, on live television.
