Hulu’s Castle Rock is a modern puzzle box built from Stephen King’s classic stories. This series, which debuted in 2018, does not tell one single King tale. Instead, it creates an original mystery using the author’s most famous fictional town as its setting. It pulls together characters, places, and ideas from across King’s “multiverse,” with the infamous Shawshank State Penitentiary from The Shawshank Redemption at its very center. For fans, the show is a treasure hunt of references. For new viewers, it’s a tense, standalone horror story about a town with a very dark history.
Shawshank Prison: More Than Just a Setting
In Castle Rock, Shawshank is not just a backdrop; it is a main character that shapes the entire town. The story begins when a death row attorney named Henry Deaver gets a call from the prison. A mysterious, silent young man, known only as “The Kid”, has been found locked in a cage deep beneath the prison. This discovery pulls Henry back to his troubled hometown and directly into Shawshank’s shadow.
The show’s creators wanted the prison to feel physically connected to Castle Rock. They filmed at a real prison to show houses literally in its shadow, making the town feel like a “company town where the business is incarceration”. This version of Shawshank exists decades after the events of The Shawshank Redemption. The show confirms that the iconic story of Andy Dufresne’s escape and Warden Norton’s corruption is part of its history. In the first episode, a guard giving a tour starts to say, “You can still see the bullet hole where Warden Norton…” before being cut off. This directly ties the series to the film’s climax where the corrupt warden kills himself.
“We wanted to look at a small town that has had terrible things happen in it and to it… What we thought Castle Rock might look like now was a sign of the death of the American small town.” – Sam Shaw, showrunner.
A Web of Characters and Cross-Story References
Castle Rock connects to The Shawshank Redemption through its setting, but it weaves a much wider web by including characters from other King books. This makes the town feel lived-in and historically terrifying.
A key figure is Alan Pangborn, the former sheriff of Castle Rock played by Scott Glenn. Pangborn is a major character in King novels like Needful Things and The Dark Half. In the series, he is retired but remains deeply involved in the town’s mysteries, linking the new story to past events from other tales.
Other character connections create a dense network of references:
- Jackie Torrance: A local woman who reveals she changed her name to honor her uncle, Jack Torrance, the infamous writer from The Shining.
- The Kid (Bill Skarsgård): His casting is a major nod, as Skarsgård had just played the clown Pennywise in the 2017 film IT.
- Sissy Spacek: She stars as Ruth Deaver, but fans know her as the original Carrie White from the 1976 film Carrie.
The series is also filled with smaller, verbal and visual “Easter eggs.” Characters mention past town tragedies like “the dog” (a reference to Cujo) and “the strangler” (referring to Frank Dodd from The Dead Zone). Henry Deaver finds old newspaper clippings with headlines about a “rabid dog” and a missing “oddity store” shopkeeper, pointing to events from Cujo and Needful Things. Even the local bar, The Mellow Tiger, is imported directly from the pages of Needful Things.
The “Schisma”: Connecting All Stephen King Stories
The deepest connection between Castle Rock and the wider Stephen King universe is not just a character or a place, but a concept. Midway through the season, the show introduces the idea of the “schisma.”
The schisma is described as a strange, ringing sound in the woods that acts as a thin spot between realities. One character explains it as “the sound of these places trying to reconcile themselves,” a doorway to “all possible pasts, and all possible presents”. This idea provides a clever narrative explanation for how Castle Rock can blend details from both King’s original books and the sometimes-different film adaptations.
Most importantly, the concept of the schisma formally introduces a Stephen King multiverse into the show. It suggests that the Castle Rock in this series is one version among many, allowing different stories and timelines to coexist. This idea lets the show respect King’s literary world while also incorporating famous elements from the films, creating a unified but flexible tapestry for all his horror stories.

A Direct Shawshank Reunion in Season 2
The connection between Castle Rock and The Shawshank Redemption became even more direct in the show’s second season. Actor Tim Robbins, who famously played the escaped convict Andy Dufresne in the 1994 film, returned to the Stephen King universe.
However, Robbins did not reprise his role as Andy. Instead, he took on the part of Reginald “Pop” Merrill, a ruthless loan shark and criminal patriarch from King’s novella The Sun Dog. Pop Merrill is a new inmate on Shawshank’s death row, bringing Robbins back inside the prison’s walls 25 years after he first escaped them on screen. This casting was a meaningful nod for fans, showing the series’ deep respect for King’s cinematic legacy while continuing to build its own original stories.
