Parker Posey is returning to horror with Sleepover, an upcoming film from Blumhouse Atomic Monster and Universal Pictures. According to an exclusive report by Variety, Posey will star in the project, which is scheduled to reach theatres on October 8, 2027. The film will be directed by Jacob Chase, whose recent work includes Insidious: Out of the Further.
Chase will direct Sleepover from a screenplay he co-wrote with Bryce McGuire, the writer of Night Swim. The film is based on an original short story by McGuire, although details about its plot and characters have not yet been disclosed. Posey is currently the only announced cast member, leaving the nature of her role and the story’s central premise under wraps.
Jason Blum is producing the film, with Chase, McGuire and Bea Sequeira serving as executive producers. Lilly Tyson is overseeing the project. Sleepover is a Cinescape Entertainment production presented by Universal Pictures and Blumhouse Atomic Monster.
Posey has appeared in several horror films over the course of her career. She played Jennifer Jolie, an eccentric aspiring star, in Scream 3 (2000) before taking on the role of the villainous vampire CEO Danica Talos in Blade: Trinity (2004). Her more recent screen credits include Thelma and Beau Is Afraid, as well as the third season of HBO’s The White Lotus.
The actress has other projects lined up alongside Sleepover. She can next be seen in Martin McDonagh’s Wild Horse Nine, which premiered at the 2026 Venice Film Festival. The Searchlight film stars John Malkovich and Sam Rockwell and is scheduled for release on November 6, 2026. Posey also hosts the upcoming reality competition series The Mob, which is set to debut on Hulu on October 26, 2026.
Sleepover reunites Chase with Blumhouse Atomic Monster following their collaboration on Insidious: Out of the Further, the sixth instalment in the long-running Insidious franchise. According to the supplied report, the film opened in August with $60 million worldwide and went on to earn $169 million globally against a reported budget of $18 million. Its domestic opening weekend brought in $25.3 million, according to Bloody Disgusting. Chase also wrote the screenplay for the film, which directly continues the story of 2023’s Insidious: The Red Door.
Following the release, Chase discussed the possibility of another instalment during a Reddit AMA, saying he had “some ideas for the next one” before adding, “We’ll see what happens!” Dread Central reported his comments. His return to the horror genre with Sleepover marks another collaboration with the production banner, although the new film is separate from the Insidious franchise based on the details announced so far.
Chase’s earlier directing credits include the 2020 horror film Come Play and the Peacock original series The Girl and the Woods. Come Play developed from his short film Larry and was released by Focus Features on October 30, 2020. The story follows a young boy who discovers an e-book about a lonely monster that manifests through electronic devices, including phones and tablets.
Made on a reported budget of $9 million, Come Play opened to $3.2 million over Halloween weekend and topped the box office during that period. Its critical reception was mixed, and the film currently holds a 56% approval rating on Rotten Tomatoes. The website’s critical consensus described it as “A frightening feature debut from Jacob Chase.” Audiences awarded the film a B-minus CinemaScore.
McGuire’s best-known credit is Night Swim, which he directed and Universal Pictures released on January 5, 2024. Produced by Jason Blum and James Wan, the film expanded on a viral 2014 short that McGuire made with co-writer Rod Blackhurst. Night Swim opened to approximately $12 million in the United States and Canada, finishing in second place behind Wonka. It eventually grossed approximately $54.8 million worldwide against a reported $15 million budget. Critical reception was largely negative, with the film holding a 19% score on Rotten Tomatoes.
Like Night Swim, Sleepover originates from an idea developed by McGuire, although the new film is based on his original short story rather than an earlier short film. Chase’s experience directing horror projects and McGuire’s background in the genre bring together the creative team behind the upcoming production. However, the filmmakers have not yet revealed how the story will unfold or what distinguishes Sleepover from other projects in the genre.
The confirmed details remain limited to Posey’s casting, Chase’s involvement as director, the creative team and the planned theatrical release date. Universal Pictures and Blumhouse Atomic Monster have not announced additional cast members, character descriptions or a plot synopsis. Sleepover is currently scheduled to open in theatres on October 8, 2027.
