Parker Posey Joins Blumhouse Horror Sleepover
Parker Posey will star in the Blumhouse Atomic Monster and Universal horror film Sleepover. Jacob Chase is directing the adaptation of Bryce McGuire's short story, which Chase and McGuire co-wrote. The movie is scheduled to hit theaters on October 8, 2027.
Posey will star in the Universal and Blumhouse Atomic Monster production Sleepover, according to Variety. Jacob Chase directs from a script he wrote with Bryce McGuire, adapting McGuire’s original short story. Jason Blum produces; Chase, McGuire, and Bea Sequeira executive produce. The film is dated for October 8, 2027. Variety has described its premise as an archetypal overnight-party horror scenario.
Chase’s earlier work includes writing and directing Come Play and Insidious: Out Of The Further. Posey began in independent cinema and has appeared in horror titles such as Scream 3, Blade: Trinity, and Beau Is Afraid. Her White Lotus season-three role earned her an Emmy nomination. Blumhouse Atomic Monster also has Curry Barker’s Anything But Ghosts in the works.
The announcement may energize horror fans and Posey admirers, potentially boosting early awareness for a film still years away. A 2027 release date could give Universal and Blumhouse time to build a campaign around Chase’s genre credentials and Posey’s renewed awards-season profile. Theater owners may see another branded horror title as a reliable draw, though actual impact may depend on marketing, reviews, and competition.
