Clay Bertrand is an alleged alias associated with two people connected to various investigations regarding regarding the assassination of President John F. Kennedy in 1963.

New Orleans attorney Dean Andrews Jr. testified to the Warren Commission on July 21, 1964 that he received a call from "Clay Bertrand," the day after the assassination of Kennedy, asking him to fly to Dallas to represent the suspected assassin, Lee Harvey Oswald. The FBI had reported two weeks after the assassination that Andrews, who had been hospitalized with pneumonia, said he was under heavy sedation and had concluded that the call had been a "figment of his imagination".

Nearly three years later on March 2, 1967, the New Orleans district attorney Jim Garrison asserted that "Clay Bertrand" was actually New Orleans businessman Clay Shaw who had conspired with Lee Harvey Oswald and David Ferrie to kill Kennedy. Shaw, who had been arrested and booked with conspiracy to commit murder, denied that he had never used the name. An FBI document to President Lyndon Johnson's advisor W. Marvin Watson at the time of this development indicated that they had been unable to locate an individual with name "Clay Bertrand".

Clay Laverne Shaw (March 17, 1913 – August 15, 1974) was a businessman in New Orleans, Louisiana. He was the only person prosecuted in connection with the assassination of President John F. Kennedy and was found not guilty.

Shaw was honorably discharged from the United States Army as a major in 1946. He served as secretary to the General Staff and was decorated by three nations: the United States with the Legion of Merit and Bronze Star, by France with the Croix de Guerre and named Chevalier de l'Ordre du Merite, and by Belgium named Chevalier of the Order of the Crown of Belgium.

After World War II Shaw helped start the International Trade Mart in New Orleans which facilitated the sales of both domestic and imported goods. He was known locally for his efforts to preserve buildings in New Orleans' historic French Quarter.

New Orleans District Attorney Jim Garrison prosecuted Clay Shaw on the charge that Shaw and a group of right-wing activists, including David Ferrie and Guy Banister, were involved in a conspiracy with elements of the Central Intelligence Agency (CIA) in the John F. Kennedy assassination. Garrison arrested Shaw on March 1, 1967. Garrison believed that Clay Shaw was the man named as "Clay Bertrand" in the Warren Commission Report. Garrison said that Shaw used the alias "Clay Bertrand" among New Orleans' gay society.

Earling Carothers "Jim" Garrison (November 20, 1921 – October 21, 1992) — who changed his first name to Jim in the early 1960s — was the District Attorney of Orleans Parish, Louisiana from 1962 to 1973. A member of the Democratic Party, he is best known for his investigations into the assassination of President John F. Kennedy (JFK).

Garrison remains a controversial figure. Opinions differ as to whether he uncovered a conspiracy behind the John F. Kennedy assassination, but was blocked from successful prosecution by a federal government cover-up, whether he bungled his chance to uncover a conspiracy, or whether the entire case was an unproductive waste of resources.

Earling Carothers Garrison was born in Denison, Iowa. His family moved to New Orleans in his childhood, where he was reared by his divorced mother. He served in the U.S. National Guard in World War II, then obtained a law degree from Tulane University Law School in 1949. He worked for the Federal Bureau of Investigation (FBI) for two years and then returned to active duty with the National Guard. After fifteen months, he was relieved from duty. One Army doctor concluded he had a "severe and disabling psychoneurosis" which "interfered with his social and professional adjustment to a marked degree. He is considered totally incapacitated from the standpoint of military duty and moderately incapacitated in civilian adaptability." Although one doctor did recommend that Garrison be discharged from service and collect 10% permanent disability, Garrison opted instead to join the National Guard where his record was reviewed by the U.S. Army Surgeon General who “found him to be physically qualified for federal recognition in the national army.”

William Oliver Stone (born September 15, 1946) is an American film director, producer and screenwriter. Stone became well known in the late 1980s and the early 1990s for directing a series of films about the Vietnam War, in which he had previously participated as an infantry soldier. He won further attention - and controversy - with films JFK (1991) and Natural Born Killers (1994). Stone's movies frequently focus on contemporary political and cultural issues. He has received three Academy Awards: Best Adapted Screenplay for Midnight Express (1978), and Best Director for Platoon (1986) and Born on the Fourth of July (1989). British newspaper The Guardian described Stone as "one of the few committed men of the left working in mainstream American cinema." Stone's films often combine different cameras and film formats within a single scene (including VHS and 8 mm film) as evidenced in JFK and Natural Born Killers.
