Sony has secured the film rights for Mouthwashing, the popular independent horror video game that debuted in 2024. The studio has brought on Karyn Kusama, known for her work on the television series Yellowjackets, to direct the adaptation.
Matt Manfredi and Phil Hay are attached to write the screenplay, with Crooked Highway serving as the production company. As of now, no cast members have been announced, and it remains unclear whether the film will adhere closely to the game's narrative.
Mouthwashing achieved critical acclaim following its release and had sold over 500,000 copies on PC by February 2025. The game recently became available on consoles.
This move by Sony follows the successful cinematic adaptation of the indie horror game Iron Lung, produced by Markiplier Studios, which garnered significant attention at the box office. The prospect of a Mouthwashing film raises questions about narrative faithfulness and potential casting choices for its characters.
