Sadie Sink's upcoming film "The Guest" is not based on a true story. It adapts Emma Cline's 2023 novel of the same name, a work of fiction that follows a 22-year-old grifter named Alex navigating a Hamptons summer after an older, wealthy man casts her out, as confirmed by Publishers Weekly's listing for the novel. The confusion is understandable: the story reads like it could be real, with the kind of specific, grounded detail that makes literary fiction feel like reportage. But Cline wrote "The Guest" as a novel, not a memoir or journalistic account, and the film in development reportedly starring Sink is adapting that fictional source material.

What "The Guest" Actually Is
"The Guest" is a 304-page literary thriller published by Random House on May 16, 2023, according to Publishers Weekly. It follows Alex, a young woman who improvises her way through a wealthy Long Island summer community after being abandoned by an older lover, inventing new identities and cover stories to stay afloat. Critics have placed the novel alongside Patricia Highsmith's "The Talented Mr.
Ripley" and the work of Joan Didion, comparisons that signal a deliberate literary-thriller style rather than a true-crime basis, per Kirkus Reviews. Those are genre touchstones for stories about con artists and reinvention, not labels applied to nonfiction. The book also earned a shortlist nod for the National Book Critics Circle's John Leonard Award, a prize given to debut fiction and nonfiction, which further situates "The Guest" as a recognized published novel rather than a biographical or journalistic work, according to the Publishers Weekly listing.
Why the Book Reads Like It Could Be Real
Part of what fuels "true story" questions is how deliberately unspecific Cline's novel is about its own setting. Reviewers have pointed out that the book never explicitly names its real-world location and avoids terms like "sex worker" or "Hamptons" outright, according to the San Francisco Chronicle's Datebook.
That vagueness is a craft choice, not a documentary one. By keeping identifying details loose, Cline builds a composite world that feels specific to readers familiar with wealthy summer enclaves without tying the plot to an actual place, person, or scandal that a reader could look up and verify.
Is Sadie Sink Actually Attached to the Film?
Sadie Sink is reportedly in talks to star in and produce the adaptation, with A24 and Square Peg negotiating for the rights after a bidding process that drew roughly a dozen competing offers, as reported by Deadline on October 9, 2026 and relayed by MEAWW. Lorene Scafaria, the writer-director behind "Hustlers," is reportedly in talks to write and direct, though neither her deal nor Sink's had formally closed as of that October 9-10, 2026 reporting window, per a report via Books of Brilliance. That timing lines up with Sink's larger career moment: the attachment comes right after her MCU debut as Jean Grey in "Spider-Man: Brand New Day," a role several outlets cite as context for why this adaptation is drawing attention now, according to NetflixJunkie.
- Studio: A24 and Square Peg, in negotiations
- Star/producer: Sadie Sink, deal not yet closed as of reporting
- Writer/director: Lorene Scafaria, in talks
- Source material: Emma Cline's 2023 novel "The Guest"
What Stage the Project Is Actually At
As of October 2026, the film is still in the negotiation and development stage, with no finalized cast, confirmed director, release date, or plot specifics beyond what the novel already establishes, according to Landmark Cinemas' movie news coverage. Anyone following the project should expect the plot to track the novel's premise closely, since no reporting points to a reworked storyline.
That means readers curious about the film's story can get an accurate preview by reading Cline's novel itself, since the adaptation is still being negotiated rather than shot or scripted. Formal confirmations of Sink's casting and Scafaria's directing deal would be the next concrete milestones to watch for before production details, like a release date, become meaningful to track.
