In his 1991 film JFK, Oliver Stone blamed the Kennedy assassination on the following people: the CIA, the Mafia, anti-Castro Cubans, and Lyndon B. Johnson.
Like JFK, the upcoming Parkland also tells a series of overlapping stories relating to the Kennedy assassination (Paul Giamatti plays Abraham Zapruder, the man who captured the assassination on 8mm film, Zac Efron plays the young emergency room doctor who had the unenviable task of treating Kennedy’s wounds, and Billy Bob Thorton plays a Secret Service agent who investigates the shooting). But whereas Oliver Stone likely would’ve used this material to blame the assassination on Zapruder, the doctor, and the Secret Service, Parkland—which is partly based on Vincent Bugliosi’s mammoth 1,632-page-long Reclaiming History—accepts the finding of the Warren Report and concludes that Oswald acted alone.
JFK was nominated for eight Oscars, but only one two (for editing and cinematography), mostly because of all the controversy surrounding Stone’s “everyone but Oswald” theory. It’s doubtful that Parkland, which also looks like an awards calibre film, will face the same problem with Academy voters.
