JFK is a 1991 film written and directed by Oliver Stone about the assassination of John F Kennedy and its aftermath, based around the investigation by New Orleans District Attorney Jim Garrison (Kevin Costner). After reading the Warren Report and finding it unsatisfactory, Garrison decides to launch an investigation on his own. After reviewing witness reports and interviewing some people on his own, Garrison becomes convinced Kennedy was killed by a conspiracy, and that all of the suspicious events seem to be circling a Texas Businessman named Clay Shaw (Tommy Lee Jones) who goes by the alias Clay Bertrand. Shaw has connections to Lee Harvey Oswald (Gary Oldman), the CIA, the FBI, and others.
