‘Mouthwashing’ Video Game Adaptation in the Works From Scott Derrickson, Karyn Kusama (Exclusive)
Confirmed
In Short: Karyn Kusama, director of 'Jennifer's Body,' will helm the film adaptation.

Developed by Wrong Organ and published by Critical Reflex, 'Mouthwashing' follows five crew members aboard the space freighter Tulpar after a devastating crash.
According to Hannah, who covers horror, sci-fi, and games at Collider, the game is 'bleak, grotesque, and sometimes difficult to sit through.'
The game, which launched today on multiple platforms including PlayStation 5, PlayStation 4, Nintendo Switch, Xbox Series X|S, Xbox One, and PC, has earned critical acclaim.
Matt Manfredi and Phil Hay, who previously worked with Kusama on 'The Invitation,' will adapt the game into a screenplay.
Scott Derrickson, known for his work on 'Sinister' and 'The Black Phone,' will produce alongside C.
The game has sold nearly one million units on PC and won several awards, including best narrative and players’ choice at the Horror Game Awards.
The Hollywood Reporter notes that Sony Pictures is now setting its sights on 'Mouthwashing' after successfully relaunching the Resident Evil franchise with a video game adaptation.
The game's surreal imagery and nonlinear narrative explore themes of responsibility, denial, and the consequences of unchecked power.
Industry insider Daniel Richtman reports that Screen Gems is reportedly attached to produce the project, with the studio previously releasing the film adaptation of 'Until Dawn.'
