A film adaptation of the viral found-footage films created by YouTuber Kane Parsons was announced to be in development at A24 back in 2023, with minimal updates since. But it looks like A24 is finally preparing to move full steam ahead with the project as a new report from Deadline suggests casting is underway. According to the outlet, The Penguin star Cristin Milioti and Chiwetel Ejiofor (who was so very charming in the recent Bridget Jones: Mad About the Boy) are in talks to co-star.

Reps for A24 have declined to comment on the news, so it sounds like if the two stars are circling these roles then the deals have not yet been signed or confirmed. Parsons will direct the film from a script by Roberto Patino. A24 is adapting alongside James Wan's Atomic Monster banner, Chernin Entertainment, and 21 Laps.

The Backrooms remains a mysterious project for the studio...
