Twin Peaks Meets IT: Welcome to Derry in Hulu’s 2-Part Stephen King Series

Stephen King’s work has inspired many successful TV and film adaptations, and he’s been a leading figure in American horror since his first novel, Carrie, became popular in 1974. One particularly noteworthy, but often overlooked, show on Hulu combined the eerie atmosphere of Twin Peaks with the terrifying world of It: Welcome to Derry. King’s stories have been the basis for some of the most iconic horror films ever made, including Stanley Kubrick’s The Shining and Brian De Palma’s 1976 version of Carrie.

Despite the 2026 film The Running Man, starring Glen Powell, not being a box office success and suggesting that audiences don’t always gravitate towards Stephen King’s science fiction stories, his work continues to inspire highly popular adaptations. For example, the 2025 series It: Welcome to Derry boldly expanded the It universe with a prequel set in the 1960s, and became one of the most frightening and inventive horror shows of recent years.

Before “Welcome to Derry” offered a fresh look at the Maine town central to Stephen King’s stories, another Hulu series, “Castle Rock,” tried something even bolder. It blended the eerie, small-town mystery of “Twin Peaks” with the intense horror of “Welcome to Derry,” and wove together multiple King stories by featuring iconic characters like Annie Wilkes and Ace Merrill within the town of Castle Rock.

Castle Rock Adapted Dozens of Stephen King Stories Simultaneously

The town of Castle Rock was already well-known to fans of Stephen King, having appeared in many of his books and short stories. So, it wasn’t surprising when the Hulu show Castle Rock featured characters and places from his most famous works. The show boasted a fantastic cast, including Lizzy Caplan, André Holland, Melanie Lynskey, Sissy Spacek, Tim Robbins, Rory Culkin, and Bill Skarsgard, who also starred in It: Welcome to Derry, making it a truly impressive series.

The show wasn’t simply a showcase of well-known actors revisiting classic Stephen King roles. CBS previously tried to adapt King’s 2009 novel Under the Dome into a three-season series, but it struggled to resolve its many storylines. Castle Rock avoided this pitfall by presenting a deliberately sprawling and unclear narrative. Characters’ paths crossed, but their individual stories weren’t neatly tied together.

Castle Rock’s Ambition Was Also The Stephen King Adaptation’s Undoing

Similar to Twin Peaks, which clearly inspired it, Castle Rock eventually had trouble managing its many storylines without a central plot to tie them together. Unlike the later, more focused It: Welcome to Derry, Castle Rock’s two seasons didn’t fully connect all of Stephen King’s stories. Instead, it felt more like Twin Peaks and Fringe, often teasing big reveals but not always providing the connections needed to make the stories feel complete.

Thankfully, the people who made Castle Rock always intended for it to last just two seasons, so the show’s mysterious and unresolved ending wasn’t a mistake. While It: Welcome to Derry aimed to fully explain Pennywise and the town’s history from Stephen King’s novel It, Castle Rock was designed to offer a glimpse into the town and leave viewers feeling just as unsettled and confused as they did watching Twin Peaks. In the end, Castle Rock successfully combined the vibes of both Twin Peaks and It: Welcome to Derry as planned.
