Sony Buys Mouthwashing Movie Rights and Hands Karyn Kusama a Very Broken Spaceship

By CriticalPixel · 2026-11-02

Sony Pictures has bought the film rights to Mouthwashing, a sentence that would have sounded like a bit two years ago. The game came from a small Stockholm studio, cost less than a takeaway dinner, and looked like a PlayStation disc somebody found in a flooded basement. Now Karyn Kusama is directing it and Scott Derrickson is producing. The deal moved fast, and that speed says more about the industry than any press release will.

What Sony Actually Bought

Deadline broke the deal and the package is not cheap. Sony picked up feature rights from developer Wrong Organ and publisher Critical Reflex. Kusama, whose credits include Destroyer, The Invitation, Jennifer's Body and a long run on Yellowjackets, is attached to direct. Matt Manfredi and Phil Hay are writing, the same pair who worked with her on Destroyer and The Invitation. Producing are Scott Derrickson, C. Robert Cargill and Vince Cheng through Crooked Highway, the banner behind The Black Phone, which operates under a deal at Sony's Screen Gems. That is a real horror package, not a licensing shrug.

The story stays close to the source, at least on paper. Five crew members are stranded on the space freighter Tulpar after a crash, supplies run down, and the group turns on itself while a captain lies dying in a bed he cannot leave. The game told that story out of order, with Jimmy as the worst possible narrator, and it worked because you had to assemble the truth from scenes that refused to line up. Deadline says the film's plot is under wraps, so nobody has confirmed how much of that fractured structure survives the edit.

The Numbers Behind the Deal

Deadline puts the game at an 88 Metacritic score and close to 1 million units sold, with Best Narrative and Players' Choice wins at the Horror Game Awards plus Best Hidden Gem at the New York Game Awards. Wrong Organ announced 500,000 Steam sales back in February 2025 and joked about throwing a party at 999,000. The distance between those two figures is the whole story. The movie deal landed while the game was still climbing, which almost never happens to a project this strange.

The timing is not subtle either. Mouthwashing is out on PS5, PS4, Switch, Xbox Series X|S, Xbox One and PC, and it sits on Game Pass for console and PC. Eurogamer notes the console versions arrived the day before the movie news started moving through the games press. A shadowdrop across every platform, then a Sony deal in the same cycle. Somebody at Critical Reflex planned that sequence, and it worked.

What the Fans Are Saying

The reaction online is loud and mostly delighted. Fans spent the weekend posting mock posters and arguing about casting, with one popular suggestion putting SZA in the role of Anya. Cinema Now summarized the deal for film followers and the replies filled up with people who had clearly finished the game and needed somewhere to put that feeling. That is the tell for an adaptation like this. Nobody is asking whether it should exist. They are asking who plays Swansea and how anyone films the cargo bay without wrecking the mood.

Where This Could Go Wrong

Here is the part that worries me. Mouthwashing works because it is a game about control, and the player is complicit in the thing the story is judging. Strip out the interactivity and you have a nasty chamber piece about five people and a broken ship, which is a fine movie but a different one. Kusama is a sharp pick for that material, since Jennifer's Body and The Invitation both live in the gap between social politeness and violence. The danger is a script that explains Jimmy instead of letting the audience sit in the discomfort he creates.

Derrickson producing is the interesting wrinkle. Crooked Highway made The Black Phone on a modest budget and turned it into a franchise, so the playbook here is small cast, contained location, ugly lighting, large returns. Mouthwashing fits that mold better than most game adaptations because there are no cities to render and no third act army to animate. One ship, five faces, and a lot of blood where the walls should be.

Wrong Organ is not sitting still either. The studio is building Carcass Clad, a co-op tank horror game where players crew a vehicle through a war zone, which suggests the same fixation on tight spaces and bad decisions. A film deal does not pay salaries forever, and the team still has to ship its next game while Hollywood borrows its first one.

The Read for Now

None of this is a guarantee. Game movies have burned us plenty, and the ones that land tend to keep the source's meanness instead of sanding it into a hero's journey. Mouthwashing does not have a hero. It has a man who lies to a camera, and if the film keeps that, Sony has something ugly and memorable on its hands. If it does not, we get a handsome trailer and a forgettable February slot, and the fans who made all those posters go back to posting about the game instead.
