Filmmaker Mike Flanagan is preparing a television series adaptation of Stephen King's fantasy epic saga The Dark Tower to build a shared screen universe.
Flanagan has established himself as King's most frequent screen collaborator, having directed more adaptations of the author's books than any other filmmaker. Their ongoing partnership is set to expand further with three upcoming projects currently underway, encompassing both a new film and television series.

The upcoming television adaptation of The Dark Tower represents a golden opportunity to establish the ultimate horror cinematic universe across film and television. King has described the expansive fantasy story as his masterpiece, marking it as the most extensive literary work of his career.
Although previous screen adaptations of King's work have contained subtle references and hidden nods hinting at a shared reality, Flanagan's project could provide explicit confirmation that these stories exist within the same continuity.

Connecting Stephen King's Literary Multiverse
In the source novels, King establishes that the world of Roland Deschain serves as the central pillar of his entire literary universe. Deschain, a gunslinger on a quest to defend the Dark Tower from forces of evil, carries a mission that holds the entire cosmos together.
Because the Dark Tower binds all realities, King's other novels connect to this central storyline in varying degrees. This structure establishes a literary multiverse throughout the author's body of work.

Flanagan now faces a unique opportunity to bring every Stephen King story together under a single banner. While it remains unconfirmed whether Flanagan's vision will follow this exact narrative framework, adapting the novels naturally incorporates the multiversal connections inherent in King's writing.
What Comes Next for the Shared Screen Universe
Rather than relying on isolated easter eggs, a faithful adaptation of The Dark Tower could clearly establish a unified horror universe for viewers. Flanagan's upcoming film and television slate will determine how explicitly these connected realities are brought to the screen.
King, born in 1947, is one of the most celebrated horror authors in modern literature, with dozens of bestselling novels and short story collections to his name. Flanagan previously adapted King's work in films such as Gerald's Game and Doctor Sleep, as well as directing acclaimed horror television series including The Haunting of Hill House.
