Mouthwashing, the unsettling sci-fi horror game from developer Wrong Organ, is being adapted into a feature film. The project brings a particularly intense modern horror game into cinema, with a creative team that has substantial experience in both psychological dread and character-driven genre storytelling.
Scott Derrickson, whose previous directing work includes Sinister, The Black Phone, and Doctor Strange, is attached as a producer. Yellowjackets and Destroyer filmmaker Karyn Kusama will direct the adaptation, while longtime writing collaborators Matt Manfredi and Phil Hay will handle the screenplay. The announcement arrives shortly after Mouthwashing expanded from its breakout PC audience to consoles earlier this week.
It is a notable fit for the game. Mouthwashing is not built around the kind of clean, action-oriented power fantasy often associated with blockbuster game adaptations. Its impact comes from confinement, uncertainty, fractured perspectives, and the slow exposure of deeply uncomfortable truths. Translating that material into a movie will mean preserving the pressure of its setting and the instability of its storytelling rather than simply recreating individual shocks.
A disaster aboard the Tulpar
The game follows the crew of the cargo spaceship Tulpar after a catastrophic crash leaves them stranded. Their circumstances are immediately bleak: they are trapped in a damaged vessel, their prospects for rescue are uncertain, and the crew must contend with dwindling resources as well as one another. What begins as a survival scenario becomes something far more disturbing as paranoia takes hold and details surrounding the disaster start to emerge.

That central premise gives the prospective film a powerful contained setting. The Tulpar is more than a backdrop for frightening imagery. It is an enclosed workplace, a failing shelter, and a place from which the characters cannot simply walk away. The physical environment amplifies every personal conflict. In a story where the crew's perceptions and memories matter as much as the ship's damaged corridors, confinement becomes a source of horror in its own right.
Mouthwashing also draws much of its force from a nonlinear structure. Rather than offering events in a straightforward progression, it reveals context in fragments. Players piece together the crew's relationships, choices, resentments, and fears over time, with each new moment changing how earlier scenes can be understood. A film version has the opportunity to use editing, performance, sound, and production design to create a similarly disorienting experience, though it will need to find its own cinematic rhythm rather than merely duplicate the game's structure.
The strongest version of a Mouthwashing film will likely treat the Tulpar as a pressure cooker: a broken ship holding together a group of people who may be even more damaged than the machinery around them.
An acclaimed modern horror game
Wrong Organ's game rapidly earned a reputation as one of the most memorable horror releases of recent years. Its visual identity is a major part of that response. The game uses an intentionally stylized presentation that feels distinct from photorealistic survival horror, helping ordinary spaces and objects feel strange, hostile, and unreal. It creates an atmosphere that can shift from darkly comic to nauseating without losing its sense of place.
The narrative was especially celebrated. Mouthwashing won Best Narrative at the 2024 Horror Game Awards, recognition that speaks directly to why a film adaptation makes sense. There are many games with striking concepts that are difficult to condense into a feature-length story. In this case, the story's focus on a small cast, an isolated location, and escalating revelations offers a relatively natural foundation for a screenplay.
That does not mean the adaptation has an easy task. Games create intimacy differently from films. A player controls movement, lingers in rooms, notices visual details at their own pace, and can feel personally implicated in an experience even when the story is largely linear. A movie cannot reproduce that interaction. Kusama, Manfredi, and Hay will instead need to identify what makes the game's discomfort work emotionally: the tension between what characters claim, what they remember, what the audience sees, and what the Tulpar seems to be hiding.
Kusama's involvement is particularly intriguing in that respect. Her work has often explored relationships strained by violence, pressure, trauma, and distrust. A story centered on a small crew whose survival depends on cooperation while their confidence in each other collapses should offer room for both suspense and character complexity. The film has the potential to be frightening not only because of the crash and its aftermath, but because of the increasingly unbearable question of whether anyone aboard can be trusted.
A creative team with horror and thriller experience
Derrickson's producing role connects the project to a filmmaker strongly associated with modern supernatural and psychological horror. Sinister and The Black Phone both demonstrate an interest in dread that accumulates gradually, using mood and implication alongside more immediate scares. That sensibility could suit Mouthwashing, whose horror is not dependent on a single monster or easily explained threat.
Manfredi and Hay bring an established partnership to the script. Their history with Kusama should also be useful for a project that will require a unified approach to tone. The source material moves through grim humor, workplace resentment, bodily horror, space-age isolation, and emotional devastation. Holding those elements together is likely to be more important than turning every memorable game moment into a literal scene.
No cast, release window, distributor, or production start date has been announced. Those missing details leave plenty of questions about what the final film will look like and how closely it will follow the game. There is also no indication yet of whether the adaptation will preserve the game's exact visual style, pursue a more realistic spacecraft aesthetic, or land somewhere between the two.
For now, the confirmed creative lineup suggests that the filmmakers understand Mouthwashing as more than a recognizable horror title. It is a story with a deliberately uncomfortable perspective, a specific atmosphere, and a narrative that depends on withholding and recontextualizing information. Those are qualities that can be weakened if treated as simple plot twists, but they can be powerful in the hands of a director willing to let ambiguity and unease breathe.
Video game horror continues its move into theaters
The Mouthwashing announcement arrives during a busy period for horror game adaptations. Horror has become one of the most adaptable corners of gaming for film, in part because its concepts are often immediately understandable: a dangerous place, a trapped protagonist, a mystery, and an escalating threat. Yet the most successful adaptations tend to recognize that a familiar premise is not enough. They need a clear point of view.
Recent years have seen audiences return to game-based scares through films such as Five Nights at Freddy's and Exit 8. Zach Cregger's Resident Evil, released in September, offered another new take on the long-running Raccoon City horror universe. These projects vary widely in tone, scale, audience expectations, and relationship to their games, but together they show that studios and filmmakers are increasingly looking beyond traditional action franchises for gaming material with a built-in genre identity.
Mouthwashing stands apart from many of those properties because its reputation is tied so closely to its narrative presentation. It is a smaller, more claustrophobic story than the sprawling worlds of Resident Evil or BioShock. That could be an advantage. Rather than needing to introduce an enormous mythology, the movie can concentrate on a single disaster, a handful of people, and the awful consequences of what happened before the audience arrived.
The broader video game film pipeline includes major projects based on The Legend of Zelda, BioShock, and Elden Ring. Each presents a different adaptation challenge, from translating fantastical adventure to capturing vast and cryptic worldbuilding. By comparison, Mouthwashing offers a concentrated nightmare. Its power lies in being trapped with the characters, unable to escape the ship or the implications of the past.
Why the Tulpar could make for unforgettable screen horror
Space horror has always benefited from the contrast between technological sophistication and human vulnerability. A cargo ship may be designed for deep-space travel, but a crash can reduce it to a fragile maze of dark rooms, malfunctioning systems, and failing supplies. In Mouthwashing, that vulnerability is heightened by the fact that the greatest danger is not necessarily external. The crew's emotional and moral collapse is inseparable from the physical catastrophe around them.
That is where the adaptation could find its most distinctive voice. A conventional survival thriller might focus on repair plans, rescue signals, and the practical mechanics of staying alive. Those elements matter, but Mouthwashing is defined by what survival does to people when they are forced to remain close to one another after trust has been destroyed. The film can make viewers feel the distance between crew members even while they occupy the same narrow corridors.
There is no word yet on when audiences will get to see the Tulpar on screen. Still, with Derrickson producing, Kusama directing, and Manfredi and Hay writing, the project has assembled a team capable of approaching the material as a character-focused horror story rather than a routine space thriller. For fans of the game, the key question will be whether the film can retain the sickening uncertainty that made the original so effective.
If it can, Mouthwashing may become one of the more singular entries in the expanding world of video game adaptations: not just a horror movie set in space, but a disturbing journey into guilt, paranoia, and the terrible things people reveal when there is nowhere left to run.
