Originally, Tom Hanks was going to play the old Paul Edgecomb but the makeup tests did not make him look credible enough to be an elderly man. Dabbs Greer was cast instead as the older Paul Edgecomb.
Tom Hanks stayed in character as Paul Edgecomb whenever Stephen King visited the set. King asked him if he would like to sit in Old Sparky, but Hanks refused since he is in charge of the block.
In actuality, Michael Clarke Duncan was of a similar height as his co-star David Morse and was a couple of inches shorter than James Cromwell. Among other things, creative camera angles were used to create the illusion that Duncan as John Coffey towered over the prison staff, even Brutal Howell and Warden Moores.
When the producers were having trouble finding the right actor to fill the role of John Coffey, Bruce Willis suggested Michael Clarke Duncan, with whom he had co-starred in Armageddon (1998).
According to director Frank Darabont, Doug Hutchison (Percy) was given the squeakiest shoes he had ever heard. He thought this was the greatest bit of fate, and a "perfectly wonderful, annoying character trait" that he kept it in the movie, and you can hear sometimes how loud his shoes are.
The reason Stephen King serialized "The Green Mile" was because it was a deliberate response to fans who flipped to the end of his books, something his mother used to do. The fans would have to wait for the last installment to find out the ending. King wrote each one with its own miniature climax, but even he admitted he did not have a clue how the story would end.
Rodney Barnes was Michael Clarke Duncan's stand-in. According to Barnes, he sneaked onto the set by hiding in the paddy wagon. He surprised director Frank Darabont and asked for a job. Darabont was impressed with Barnes' effort and hired him. Barnes wanted to work on the film so that he could meet his favorite author, Stephen King.
Tom Hanks accepted the role of Paul Edgecomb in this film as a favor to Frank Darabont, after he was forced to turn down the role of Andy Dufresne in The Shawshank Redemption (1994) in order to play the title role in Forrest Gump (1994).
More than thirty works of Stephen King have been adapted to movies, but this was the only one to have broken the $100 million mark at the North American box office (as of November 2007).
When Stephen King visited the set of this film, he asked to be strapped into Old Sparky to see how it felt. He did not like it and asked to be released.
When Paul and Brutal take John Coffey outside at night, John looks at the stars and says, "Look Boss, it's Cassie, the lady in the rocking chair." This is a reference to the constellation Cassiopeia. In Greek mythology, Queen Cassiopeia is often depicted as sitting in a chair or rocking chair.
According to the novel by Stephen King, Percy Wetmore is supposed to be 21 years old. During production, Doug Hutchison (Percy) was 39 years old. He told director Frank Darabont he was in his early/mid 30s. When he went to audition for The Salton Sea (2002), the director for that film told him he was "too young," at which point Hutchison showed his driver's license to prove his age.
The name for the character John Coffey was lifted from a college professor, Rev. John Coffee. Stephen King had met him once and really liked his name and used it in "The Green Mile." Reverend Coffee taught history classes at Emerson College in Boston, Massachusetts and retired in May 2005.
Harry Dean Stanton appeared in this film. There is a character named "Harry," and another named "Dean Stanton." This is merely a coincidence, since the characters' names existed in the book long before Harry Dean Stanton was even cast in the movie.
The music played over the loudspeakers in the retirement home as Old Paul Edgecomb first walks out of his room is the same as the music the nurses played at medication time in One Flew Over the Cuckoo's Nest (1975). The music used is Mantovani's Charmaine.
At the beginning of the movie, when the old Paul Edgecomb is walking to get some breakfast after waking from that bad dream, he is walking on a tiled floor that is very green, as if it is his Green Mile.
While many of Stephen King's novels are set in the author's native Maine, The Green Mile (1999) takes place in Louisiana. However, the surname of the main character, Edgecomb, is the name of a town on Maine's mid-coast.
Stephen King's original novel 'The Green Mile' was published in 100-page paperback installments between March and August of 1996. He had begun developing the story while writing Desperation, and needed to finish that novel but still wanted to see where his death row story would go. Ralph Vicinanza, a friend of King's who sells foreign publication rights, had recently had a discussion with another friend in England about Charles Dickens, in which he learned that Dickens often published his novels in installments in newspapers and magazines, and it had been suggested that, in the U.S., someone like Stephen King could try writing a book that way. Vicinanza was under the impression that no recent novels had been written this way. He was in fact mistaken. Tom Wolfe had published his first draft of The Bonfire of the Vanities (1990) in installments in Rolling Stone. Both that novel and this one were turned into films starring Tom Hanks. This also ended up not being Stephen King's only story published in installments: his Dark Tower series spanned seven full-length books, published over the course of 30 years, from 1982 until 2012.
Doug Hutchison (Percy) made a $20 bet with the extras (behind the scenes) during Del's execution that they couldn't recite his lines. Unknowingly, Tom Hanks wrote Hutchison's lines on big cue cards behind him. He caught on to the joke when the extras kept laughing. By the end of the day, Hutchison owed at least $60 to different people.
It's ironic that when Percy first encounters Mr. Jingles he calls him 'scurvy' which is a condition caused by lack of vitamin C. Mice have an active gene that synthesizes vitamin C.
The film flips the action of the first two installments of the novel. The first book, "The Two Dead Girls," begins with John Coffey arriving on the Mile, but at this point Arlen Bitterbuck has already been executed and Eduard Delacroix already has his mouse. The second book goes back to before John's arrival and tells of Bitterbuck's fate and the origins of the mouse.
This movie features three actors who have portrayed real-life U.S. Presidents: David Morse played George Washington in John Adams (2008), Gary Sinise played Harry S. Truman in Truman (1995) and James Cromwell played George H.W. Bush in W. (2008).
The character of John Coffey was named for Emerson College faculty member and Professor Emeritus of History John M. Coffee Jr., who Stephen King was introduced to by a student.
The crew made a small cannon to shoot chocolate goo at David Morse. The goo hit Morse so hard it went up his nose, in his eyes, and into his mouth. Morse wasn't amused, as he's allergic to chocolate.
Mr. Jingles isn't pushing the spool. It's being pulled by a rig that was erased with special effects. The mouse is following a scent that was applied to the spool.
That giant brick wall in the background of the prison is made out of lightweight fiberglass. All the walls could be moved to make room for cameras and lighting.
Frank Darabont controlled the lightning machine himself to create all the flashes. "I have a little control panel with buttons on it and I get to go crazy."
The trivia items below may give away important plot points.
Michael Clarke Duncan was uncomfortable with having to grab Tom Hanks' crotch for the scene where he takes his infection away. Hanks left the set and came back to do the scene, Duncan grabbed at Hanks' crotch and was shocked to discover that Hanks had put an empty water bottle in his trousers. After that, Duncan felt more comfortable with the scene.
By the time Paul introduced Elaine to Mr. Jingles, the mouse would have to be at least 64 years old -- over nine times the age of the oldest actual mouse.
We are never actually told why Arlen Bitterbuck and Edward Delacroix were sentenced to death throughout the film. According to the novel on which the movie is based, Delacroix was an arsonist, rapist and murderer, while Bitterbuck murdered a man in an argument over a pair of boots.
When Melinda Moores (Patricia Clarkson) is visited by John Coffey (Michael Clarke Duncan), she gives him a St. Christopher medal. In Catholicism, St. Christopher is known as the patron saint of travelers (John Coffey describes himself as a wanderer), and, like Coffey, died a martyr.
In the book, Paul's wife is killed in a major bus accident, and Paul is one of four only survivors. It is highly hinted that Paul survived because of the power John gave him.
The plot unfolds in the form of Paul telling Elaine the story of the Green Mile. In the book, Paul writes his story down in the form of a novel. At the end of the film, as Paul leaves the cemetery after Elaine's burial, a tombstone can be seen behind him that reads "Greene", and two others, one in the foreground and one to the right of the screen, that read "Story".
Michael Jeter taught himself how to say "The Lord's Prayer" in Creole to add authenticity to his character's Cajun heritage. You can hear him quietly reciting it during Del's execution scene, as the dry sponge is being applied to his head.
In Doctor Sleep, Stephen King's sequel to The Shining, when Danny Torrance senses that someone is dying, he experiences it as insects, flies, In the same way that flies come out of John Coffey's mouth when he heals people. In Doctor Sleep, Danny even speaks Percy's line, "Dead man walking." Also in Doctor Sleep, flies portend something bad about to happen, much as before Percy is institutionalized.
