What follows is one of the most memorable monologues in modern cinema. Sutherland, reportedly spending four months preparing for this brief but pivotal role, unleashes a torrent of information with a calm intensity that belies the explosive nature of his words. He paints a picture of a vast conspiracy, implicating the CIA, the military-industrial complex, and even elements within the U.S. government in Kennedy’s death. “The organizing principle of any society, Mr. Garrison, is for war,” he declares, suggesting that JFK’s push for peace—his refusal to escalate the Vietnam War, his détente with the Soviets—made him a target of those who thrived on conflict.
Intercut with Sutherland’s narration are flashes of historical footage and dramatized recreations: Kennedy’s motorcade in Dallas, the Zapruder film’s infamous headshot, and glimpses of shadowy figures plotting in back rooms. John Williams’ pulsing score heightens the tension, while Stone’s frenetic editing mirrors the overwhelming scope of the conspiracy Mr. X describes. For Garrison—and the audience—it’s a moment of shattering clarity, as the assassination transforms from a lone gunman’s act into a coup d’état orchestrated to install Lyndon B. Johnson in the Oval Office.
Sutherland’s delivery is masterful, balancing precision with urgency. He barely pauses for breath, yet every word lands with purpose, drawing Costner’s Garrison (and viewers) deeper into the rabbit hole. Costner, for his part, plays the foil perfectly—his wide-eyed silence and subtle shifts in expression conveying a man grappling with the enormity of what he’s hearing. It’s a testament to both actors’ skill that the scene, despite its length and density, never feels like an exposition dump; instead, it’s a gripping exchange that propels the film into its climactic final act.
