JFK is a 1991 American epic political thriller film co-written and directed by Oliver Stone. The film examines the investigation into the assassination of John F. Kennedy by New Orleans district attorney Jim Garrison, who came to believe there was a government conspiracy to assassinate Kennedy and that Lee Harvey Oswald was a scapegoat.
The film's screenplay was adapted by Stone and Zachary Sklar from the books On the Trail of the Assassins by Garrison and Crossfire: The Plot That Killed Kennedy by Jim Marrs. Stone described this account as a "counter-myth" to the Warren Commission's "fictional myth". JFK's embrace of conspiracy theories made it controversial.
