Leonardo DiCaprio is about to give Oliver Stone a run for his money.
Hot off the box office success of Inception, the Hollywood star's production company has just landed the film rights to Legacy of Secrecy, a book positing that the mafia was behind President John F. Kennedy's 1963 assassination.
Keep an eye on that grassy knoll.

DiCaprio's rep confirmed to E! News that the thesp will star in and produce the Warner Bros. thriller via his production shingle, Appian Way. The actor's idea to adapt the tome, whose full title is Legacy of Secrey: The Long Shadow of the JFK Assassination, came from his father, George, who introduced it to him years ago.
DiCaprio will play FBI informant Jack Van Laningham who, according to recently declassified FBI files, took part in a dangerous undercover operation to infiltrate the mafia organization of crime boss Carlos Marcello, who was active in Texas and Louisiana during the 1960s.
In his role as an informant, Van Laningham alleged Marcello confessed to him that he was behind Kennedy's murder and that he even had a hand in the assassination of Martin Luther King Jr. and the Watergate scandal.
After the commander in chief was gunned down in Dallas' Dealey Plaza, the feds rounded up a number of Marcello's family members and associates for questioning, but no charges were ever brought against them. And while the Warren Commission failed to mention him, the mob boss was singled out by the 1979 Hosue Select Committee on Assassinations as having "had the motive, means and opportunity" to kill Kennedy.
If all goes as planned, Legacy of Secrecy will hit theaters in 2013 to coincide with the 50th anniversary of the president's death.
