get all the rights to the film and put up $20 million for the budget. The director did this so that the screenplay would not be widely read and bid on, and he also knew that the material was potentially dangerous and wanted only one studio to finance it. Finally, Stone liked Semel's track record of producing political films. Screenplay When Stone set out to write the screenplay, he asked Sklar (who also edited Marrs' book) to co-write it with him and distill the Garrison and Marrs books and Rusconi's research into a script that would resemble what he called "a great detective movie." Stone told Sklar his vision of the film: Although he did employ ideas from Rashomon, his principal model for JFK was Z: Stone broke the film's structure down into four stories: Garrison investigating the New Orleans connection to the assassination; the research that revealed what Stone calls, "Oswald legend: who he was and how to try to inculcate that"; the recreation of the assassination at Dealey Plaza; and the information that the character of "X" imparts on Garrison, which Stone saw as the "means by which we were able to move between New Orleans, local, into the wider story of Dealey Plaza." Sklar worked on the Garrison side of the story while Stone added the Oswald story, the events at Dealey Plaza and the "Mr. X" character. Sklar spent a year researching and writing a 550-page triple-spaced screenplay and then Stone rewrote it and condensed it closer to normal screenplay length. Stone and Sklar used composite characters, most notably the "Mr. X" character played by Donald Sutherland. This was a technique that would be criticized in the press. He was a mix of Richard Case Nagell and retired Air Force colonel Fletcher Prouty, another adviser for the film and who was a military liaison between the CIA and the Pentagon. Meeting Prouty was, for Stone, "one of the most extraordinary afternoons I've ever spent. Pretty much like in the movie, he just started to talk." According to Stone: The screenplay's early drafts suggested a four and a half-hour film with a potential budget of $40 million – double what Stone had agreed to with Warner Bros. The director knew film mogul Arnon Milchan and met with him to help finance the film. Milchan was eager to work on the project and launch his new company, Regency
