Reclaiming History: The Assassination of President John F. Kennedy is a book by attorney Vincent Bugliosi (Norton, 2007; 1,632 pages; ISBN  ) that analyzes the events surrounding the assassination of John F. Kennedy, focusing on the lives of Lee Harvey Oswald and Jack Ruby.
 The book is drawn from many sources, including the Warren Report.
 Bugliosi's 1,632-page, 1,535,791-word book (with a CD-ROM containing an additional 1,000+ pages of footnotes) analyzes all aspects of the assassination and the rise of the conspiracy theories about Kennedy's assassination in the years subsequent to the event.
 Bugliosi argues that the Warren Commission's conclusion that Lee Oswald acted alone in shooting Kennedy is correct.
 The book won the 2008 Edgar Award for the Best Fact Crime category.
Parkland is a 2013 American historical drama film that recounts the chaotic events that occurred following John F. Kennedy's assassination.
 The film is written and directed by Peter Landesman, produced by Playtone's Tom Hanks and Gary Goetzman, and Bill Paxton with Exclusive Media's Nigel and Matt Sinclair.
 The film is based on Vincent Bugliosi's 2008 book "Four Days in November: The Assassination of President John F. Kennedy".
The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established by President Lyndon B. Johnson through Executive Order on November 29, 1963 to investigate the assassination of United States President John F. Kennedy that had taken place on November 22, 1963.
 The U.S. Congress passed Senate Joint Resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy, mandating the attendance and testimony of witnesses and the production of evidence.
 Its 888-page final report was presented to President Johnson on September 24, 1964 and made public three days later.
 It concluded that President Kennedy was assassinated by Lee Harvey Oswald and that Oswald acted entirely alone.
 It also concluded that Jack Ruby also acted alone when he killed Oswald two days later.
 The Commission's findings have proven controversial and have been both challenged and supported by later studies.
Derry is a fictional town and a part of Stephen King's fictional Maine topography.
 Derry has served as the setting for a number of his novels, novellas, and short stories.
 Derry first appeared in King's 1981 short story "The Bird and the Album" and has reappeared as late as his 2011 novel "11/22/63" (see list below).
 Derry is said to be near Bangor, but King has acknowledged that Derry is actually his portrayal of Bangor.
 A map on King's official website, though, places Derry in the vicinity of the town of Etna.
King Kennedy is an upcoming drama thriller film set in the 1960s made entirely from archive material.
 The film stars some of the most prominent characters from 1960s America, including US President John F. Kennedy, Robert F. Kennedy, the civil rights movement leader Martin Luther King, convicted assassins Lee Harvey Oswald and Sirhan Sirhan and the film world's brightest icons of that time Marilyn Monroe and Frank Sinatra.
 The plot line revolves around the concepts of truth and freedom, but pursues further towards deception, intrigue, conspiracy and murder, and features some of the most memorable moments in 1960s America, including Marilyn Monroe's world-famous "Happy Birthday, Mr. President" at Madison Square Garden and Martin Luther King's "I Have A Dream" speech on the steps of the Lincoln Memorial in which he called for racial equality and an end to discrimination.
 The film is designed primarily to remind, focusing on the characters and events that build up to the assassinations of John F. Kennedy, Robert F. Kennedy and Martin Luther King as their apparent determination to shy away from war, discrimination and hatred became ever more publicized.
