Mouthwashing Horror Game Could Get a Sony Movie Adaptation, Report Claims

Mouthwashing, the psychological horror game that has attracted hundreds of thousands of players, could be heading to the big screen. According to industry insider Daniel Richtman, Sony is preparing a film adaptation of the unsettling space-horror title, with Screen Gems reportedly attached to produce the project.

Screen Gems previously released the film adaptation of Until Dawn, another horror property originating in video games. However, the reported Mouthwashing adaptation has not been officially confirmed by Sony in the supplied information. Details about the screenwriter, director, cast, and potential release date also remain unknown.

The reported project could introduce the game’s disturbing narrative to a wider audience, bringing its claustrophobic setting and psychological tension to a different medium.

Mouthwashing Movie Adaptation: What We Know So Far

According to Richtman’s report, Screen Gems is expected to handle the film adaptation of Mouthwashing. The studio’s previous involvement with Until Dawn makes the reported project particularly interesting for fans of horror games transitioning to cinema.

At present, however, the available information is limited. No screenwriter or director has been named, and there are no confirmed details about casting, production dates, or a theatrical release window.

The reported adaptation should therefore be treated as a project in the early stages of development rather than a fully announced movie with an established production schedule.

What Is Mouthwashing About?

Developed by the Swedish studio Wrong Organ with support from publisher Critical Reflex, Mouthwashing is a psychological horror game set aboard a space freighter called the Tulpar.

The ship is transporting a cargo of mouthwash when a catastrophic crash leaves its five crew members isolated from outside help. With food and energy supplies running low, the survivors face increasingly desperate circumstances as tension grows within the group.

Captain Curly becomes a central figure in the unfolding tragedy. After suffering horrific injuries in the disaster, he becomes completely dependent on the other crew members, some of whom blame him for the catastrophe that has left them facing an uncertain fate.

The narrative moves between events before and after the crash, gradually revealing the circumstances behind the disaster, the crew members’ histories, and the relationships that shape their decisions.

Rather than relying solely on conventional jump scares, the game builds its horror through psychological distress, unreliable perspectives, and the deterioration of relationships under extreme pressure.

These elements could provide a distinctive foundation for a movie adaptation, although it remains unclear how closely a potential film would follow the original story.

Why a Mouthwashing Film Could Interest Horror Fans

The premise of Mouthwashing combines the isolation of a spaceship setting with a character-driven psychological nightmare. With five crew members trapped in a deteriorating situation, the story offers opportunities to explore guilt, responsibility, desperation, and the consequences of survival decisions.

A film adaptation would also face the challenge of translating the game’s shifting timeline and disturbing atmosphere into a cinematic narrative.

Screen Gems’ reported involvement may attract attention because of its connection to Until Dawn. However, no creative team or adaptation approach has been confirmed, so it is too early to assess how the movie might handle the source material.

For now, fans will have to wait for further details before knowing whether the project will move into production.

Mouthwashing Expands to More Gaming Platforms

While the reported movie adaptation remains unconfirmed, the game itself is reaching additional platforms.

According to the supplied announcement, Mouthwashing is scheduled to arrive on PlayStation 4, PlayStation 5, Xbox Series X|S, and Nintendo Switch on October 29, 2026. The release is also set to coincide with its addition to the Xbox Game Pass catalogue.

The game originally launched on PC in September 2024 and has reportedly sold more than 800,000 copies on Steam.

The expanded platform release gives more players an opportunity to experience the psychological horror story, while the reported film project could eventually bring its unsettling narrative to an entirely different audience.
