Sony Pictures is developing a feature film adaptation of the psychological horror videogame “Mouthwashing.” The project is based on the game created by Sweden-based developer Wrong Organ and published by Critical Reflex, with Sony acquiring the film rights.
The adaptation is being steered by director Karyn Kusama, with Matt Manfredi and Phil Hay writing the screenplay. Scott Derrickson and C. Robert Cargill, along with Vince Cheng, are producing under their Crooked Highway banner, alongside additional production involvement referenced in coverage. Outlets largely align on the core announcement—Sony’s rights acquisition and the involvement of Kusama and the key production team.
Differences in emphasis are limited: one source highlights the full package of directing and writing talent, while the other focuses more narrowly on the fact that the adaptation is in development and underscores the identities of Derrickson and Kusama as the headline draw.
