The scene with the leeches and the area that Gordie was attacked was based on a real life experience that Stephen King had. Mr King has stated that he even has the scar to prove it.

While practicing his lines, Jerry O'Connell was incredibly impressed that, as an 11-year old, he was being allowed to swear.

While filming the scene in which Vern and Gordie are being chased by a train, director Rob Reiner couldn't get Jerry O'Connell and Wil Wheaton to look scared enough, so he proceeded to yell at them until they began to cry, then filmed the scene again.

Castle Rock is really called Brownsvillie town in Brownsvillie town, Oregon.

The character of Ray Brauer is based on a real friend of Stephen King's who died in a motorcycle accident when he was about 20 years old. His name was Raymond Von Brauer, and his full name also appears in the Stephen King short story that this film is based on, titled: "The Body"

Kiefer Sutherland stayed in character off-camera by often picking on Wil Wheaton, River Phoenix, Corey Feldman, and Jerry O'Connell.

In the book, Vern had been looking for his pennies for four years. It was shortened to nine months in the movie to be more realistic.
