The 1991 Kevin Costner movie JFK managed to stir up so much controversy that the historical drama changed real-life US law. 1991’s JFK saw director Oliver Stone take on his most ambitious task yet. Fresh off the critical success of Platoon, Wall Street, and Born on the Fourth of July, Stone adapted Jim Garrison’s non-fiction book On the Trail of the Assassins and Jim Marrs’ Crossfire: The Plot That Killed Kennedy into an epic 188-minute political thriller that aimed to finally explain the persistent mysteries surrounding JFK’s 1963 assassination.
