Sadie Sink's Next Film: A24's Adaptation of Emma Cline's 'The Guest'

Sadie Sink’s surprise appearance as Jean Grey in Spider‑Man: Brand New Day has already turned heads, and the actress is now poised for her next big move. She has entered talks to star in and produce A24’s film adaptation of Emma Cline’s novel The Guest. The project marks Sink’s first credit as a feature‑film producer and shifts her from superhero spectacle to a prestige drama. If the adaptation proceeds, it could redefine her career trajectory beyond the MCU.

What happened

Sadie Sink, who debuted in the MCU as Jean Grey in Spider‑Man: Brand New Day, is in advanced discussions to both star in and co‑produce The Guest, an upcoming feature from A24 and Square Peg. The novel, written by Emma Cline and longlisted for the PEN/Faulkner Award, was acquired by A24 earlier this year, and writer‑director Lorene Scafaria is reported to be attached to helm the adaptation.

The Guest follows Alex, a calculating grifter and escort navigating a world of precarity and survival. Critics praised the book for its sharp prose and complex protagonist, naming it one of the best books of the year across multiple publications. Sink, a self‑confessed fan of the novel, reportedly lobbied for the role as soon as the film rights were secured.

Industry observers note that the timing is strategic: after the commercial success of Brand New Day, Sink’s involvement in a prestige drama allows her to showcase range while gaining production experience before the next wave of MCU multiverse projects.

Why it matters

Sink’s move signals a broader trend of MCU talent seeking credibility outside the superhero genre, potentially influencing casting decisions for future franchise entries. By taking on a producer role, she gains creative control and diversifies her portfolio, which could open doors to more behind‑the‑scenes opportunities. For A24, attaching a high‑profile MCU star brings mainstream attention to a typically niche, auteur‑driven slate, potentially expanding its audience.

How to think about it

Fans should view The Guest as a test of Sink’s versatility rather than a departure from the MCU. Tracking the film’s development—casting announcements, director confirmation, and production timelines—will give clues about how studios balance franchise obligations with prestige projects. For aspiring actors, Sink’s dual role illustrates the value of leveraging blockbuster visibility to secure creative authority on smaller‑scale films.
