Sony Pictures Acquires Film Rights to Psychological Horror Game Mouthwashing; Karyn Kusama to Direct

Sony Pictures has secured feature film rights to the psychological horror video game Mouthwashing from developer Wrong Organ and publisher Critical Reflex. Acclaimed filmmaker Karyn Kusama, known for Destroyer and Jennifer's Body, is attached to direct, with Matt Manfredi and Phil Hay writing the screenplay. The producing team includes Scott Derrickson, C. Robert Cargill, and Vince Cheng under their Crooked Highway banner, which has a first-look deal with Sony. Mouthwashing, which gained a cult following for its unsettling narrative and unique aesthetic, explores themes of isolation and psychological unraveling aboard a stranded spaceship. This adaptation underscores Hollywood's growing appetite for indie horror games as source material, following successful transitions like Five Nights at Freddy's and The Last of Us. With Kusama's track record in tense, character-driven horror and the producing pedigree of Derrickson and Cargill, the project is poised to attract both gamers and genre fans. Sony's move signals confidence in the IP's cinematic potential and the expanding crossover between interactive and linear storytelling.
