A picture of Warden Norton (Bob Gunton) from The Shawshank Redemption (1994) can be seen hanging from the wall in Shawshank prison.
Some filming took place at West Virginia State Penitentiary in Moundsville, West Virginia. The penitentiary once housed two thousand four hundred violent criminals with eighty-five executions taking place on the property, along with murder, rape, and suicides. The one hundred forty-two-year-old penitentiary is considered, to some, as one of the most haunted sites in the state.
Michael Rooker played Sheriff Alan Pangborn in The Dark Half (1993) while Ed Harris played Pangborn in Needful Things (1993). Scott Glenn portrays an older Alan Pangborn on this program.
Marc Bernardin (Fatman on Batman, comic writer, pop culturist) left his position as Entertainment editor of the "Los Angeles Times" to be a writer on the series.
The trailer for the show teased the appearance of Pennywise, the main villain in It (2017). Bill Skarsgård played that role in that film, but will be playing a different character in this show.
In the opening scene, the warden is listening to 100.3 FM. WKIT in Bangor, Maine. This is a classic rock station owned by Stephen King, along with WZON, which is also referenced in many of King's works.
The song that is playing when Warden Lacey commits suicide, "Che soave zeffiretto", Le nozze di Figaro is also heard in The Shawshank Redemption (1994) when Andy gets the shipment of books and records in for the library and barricades himself in the warden's office so he can play it over the prison's P.A. system.
This is the second time for Melanie Lynskey, Terry O'Quinn, Bill Skarsgård, Chosen Jacobs, and Sissy Spacek to be in a Stephen King adaptation. Melanie was in Rose Red (2002), Terry was in Silver Bullet (1985), Bill and Chosen in both parts of It (1990), and Sissy was in Carrie (1976).
Bill Skarsgård shot this series in between two other Stephen King projects: It (2017) and It: Chapter Two (2019).
Castle Rock is the same town where Gordie, Chris, Teddy, and Vern lived in the story Stand By Me.
Sissy Spacek's real-life daughter Schuyler Fisk plays the younger version of her mother's character Ruth Deaver. She can be seen in episode one, and also in old photos of the Deaver family.
Bill Skarsgård and Chosen Jacobs, who played Pennywise and Young Mike Hanlon respectively in It (2017), are in this series, which is also based on Stephen King stories.
Marks the second collaboration between J.J. Abrams, Stephen King, and Hulu; the first being 11.22.63 (2016).
In episode two, Henry Deaver is at the home of the deceased warden Dale Lacy looking through his belongings. He comes across a folder with news paper clippings, the headline of one reads: "Rabid Dog Tears Through Town". This is a reference to Cujo, a book written by Stephen King that was also turned into a movie.
In the "This Place" teaser trailer, if you pause it forty-three seconds in, you can see three pictures ending with a picture of Terry O'Quinn as "Dale Lacy". The first picture is Bob Gunton as "Warden Norton" from The Shawshank Redemption (1994). This leads us to believe that the "Dale Lacy" character would be the new or current warden at Shawshank Prison.
Castle Rock was also featured in The Dead Zone (1983), Stand by Me (1986), The Dark Half (1993), and Needful Things (1993), all books by Stephen King.
Scott Glenn's character of Sheriff Alan Pangborn previously appeared in Needful Things (1993), in which Ed Harris played the part. Glenn and Harris appeared in The Right Stuff (1983) and Absolute Power (1997).
