Content:  Hanks and Darabont met at an Academy Award luncheon in 1994. Stephen King stated he envisioned Hanks in the role and was happy when Darabont mentioned his name. Hanks was originally supposed to play elderly Paul Edgecomb as well, but the makeup tests did not make him look credible enough to be an elderly man. Because of this Greer was hired to play the older Edgecomb. John Travolta was offered the role of Paul Edgecomb but turned it down. Duncan credited his casting to Bruce Willis, with whom he had worked on the film Armageddon one year earlier. According to Duncan, Willis introduced him to Darabont after hearing of the open call for John Coffey. Basketball player Shaquille O'Neal was offered the role of John Coffey but turned it down.
