Stone was not interested in making a film about Garrison's life, but rather the story behind the conspiracy to kill Kennedy. He also bought the film rights to Jim Marrs' book "Crossfire: The Plot That Killed Kennedy". One of the filmmaker's primary goals with "JFK" was to provide a rebuttal to the Warren Commission's report that he believed was "a great myth. And in order to fight a myth, maybe you have to create another one, a counter-myth." Even though Marrs' book collected many theories, Stone was hungry for more and hired Jane Rusconi, a recent Yale University graduate, to lead a team of researchers and assemble as much information about the assassination as possible while the director completed post-production on "Born on the Fourth of July". Stone read two dozen books on the assassination while Rusconi read between 100 and 200 books on the subject.
