narration. Jim Garrison played Chief Justice Earl Warren, during the scene in which he questions Jack Ruby in a Dallas jail and in a TV appearance. Assassination witness Beverly Oliver, who claims to be the "Babushka Lady" seen in the Zapruder film, also appeared in a cameo in Ruby's club. Sean Stone, Oliver Stone's son, plays Garrison's oldest son Jasper. Perry Russo, one of the sources for the fictional character Willie O'Keefe, appeared in a cameo as an angry bar patron who says Oswald should get a medal for shooting Kennedy. Principal photography The story revolves around Costner's Jim Garrison, with a large cast of well-known actors in supporting roles. Stone was inspired by the casting model of the documentary epic The Longest Day, which he had admired as a child: "It was realistic, but it had a lot of stars ... the supporting cast provides a map of the American psyche: familiar, comfortable faces that walk you through a winding path in the dark woods." Cinematographer Robert Richardson was a week and a half into shooting City of Hope for John Sayles when he got word that Stone was thinking about making JFK. By the time principal photography wrapped on City of Hope, Richardson was ready to make Stone's film. To prepare, Richardson read up on various JFK assassination books starting with On the Trail of the Assassins and Crossfire: The Plot That Killed Kennedy. The original idea was to film the opening sequence in 1.33:1 aspect ratio in order to simulate the TV screens that were available at the time of the assassination, then transition to 1.85:1 when Garrison began his investigation, and finally switch to 2.35:1 for scenes occurring in 1968 and later. However, because of time constraints and logistics, Richardson was forced to abandon this approach. Stone wanted to recreate the Kennedy assassination in Dealey Plaza. His producers had to pay the Dallas City Council a substantial amount of money to hire police to reroute traffic and close streets for three weeks. He only had ten days to shoot all of the footage he needed and so he used seven cameras (two 35 mm and five 16 mm) and 14 film stocks. Getting permission to shoot in the Texas School Book Depository was more difficult. They had to pay $50,000 to put someone in the window from which Oswald was supposed to have shot Kennedy. They
