Mouthwashing : The Film (2027)

Sony Pictures has acquired the film rights to the critically acclaimed 2024 independent horror game Mouthwashing, marking a significant entry in the wave of successful video game adaptations. The project is being developed by Crooked Highway, the production company behind the hit movie The Black Phone, which was starring Ethan Hawke. This partnership aims to translate the game's intense psychological terror and surreal narrative into a cinematic experience that respects the source material while expanding its reach to a broader audience.

Director Karin Cusma, known for her work on the HBO series Yellowjackets, has been attached to helm the adaptation. She will collaborate with screenwriters Matt Manfredi and Phil Hay, whose previous credits include the Scream franchise. While specific plot details remain under wraps, the film is expected to delve into the claustrophobic nightmare of the Tulpar crew stranded in space. As of the latest announcements, the cast has not been revealed, and it remains undecided whether the screenplay will strictly follow the original game's non-linear storytelling structure or adapt it for traditional film pacing.

• The game Mouthwashing saw its PC version sell over 500,000 copies by early 2025, establishing a strong fanbase ahead of the film announcement.
• Crooked Highway previously produced The Black Phone, demonstrating their capability to handle dark, supernatural themes with critical success.
• Director Karin Cusma brings experience from Yellowjackets, a series noted for its complex character dynamics and psychological horror elements.
• The acquisition follows a trend of high-performing indie game adaptations, such as the box office success of the Iron Lung film.
• The original game was developed by Wrong Organ and published by Critical Reflex, who retained the rights until selling them to Sony.
