Al Pacino, Viggo Mortensen, John Travolta, Shia LeBeouf, Rebecca Pidgeon (“Bird Box”) and singer/actress Courtney Love have joined the cast of the JFK thriller ‘Assassination’.

The synopsis reads; 1963. During a crucial justice hearing against organized crime, the head of the Chicago mob orders the assassination of President John F. Kennedy Jr., creating a deadly conspiracy while altering the fate of a nation.

Pulitzer Prize winner and Oscar nominee Mamet (“Heist,” “Wag the Dog”) is directing from a story by himself and Nicholas Celozzi, who based the script on his great uncle, the Chicago mob boss Sam Giancana, who may have played a significant role in orchestrating Kennedy’s assassination.

Insiders indicate it will focus on events that took place 48 hours before the assassination, telling the mob’s version of the story. Celozzi based the material on details shared by his late uncle Pepe (Giancana’s brother), who suggested that the mob’s hand in the assassination was payback for the president’s alleged snubbing of Giancana and his campaign against organized crime, despite his reliance on the mob during elections.

Corey Large and Celozzi will produce, executive producers are John Burnham, Arclight Films’ Gary Hamilton and Pia Patatian, Jordan Nott, Bernie Gewissler and Amar Balaggan.

Production is scheduled to start in September in Vancouver.
