Featuring extensive stills from the actual film, the screenplay is a faithful adaptation of King's bestselling story of a death-row block at Cold Mountain Correctional Facility, called "The Green Mile" because the trip to the electric chair is called "Walking the Mile" and the floor leading to the electric chair is made of green tile. Narrated by the elderly Paul Edgecombe (Tom Hanks plays the young Paul Edgecombe), who reminisces about his days as the superintendent of death row during the 1930s. Edgecombe tells of the mysterious John Coffey (played by Armageddon's Michael Clark Duncan), a prisoner with the body of a giant and the mind of a child, who allegedly murdered two young girls. While Coffey awaits his execution, he displays odd supernatural powers that cause the inmates and guards to question their beliefs about everything they hold dear.
