The game's publisher, [Critical Reflex](https://www.killscreen.com/tag/critical-reflex/), confirmed the project in [the announcement](https://www.instagram.com/p/DfF1IfnuKFP/?ref=killscreen.com) on Oct. 29, naming Sony's Screen Gems label as producer.

Reports from [Engadget](https://www.engadget.com/2301826/sony-is-working-on-a-film-adaptation-of-viral-indie-horror-game-mouthwashing/?ref=killscreen.com) and [World of Reel](https://www.worldofreel.com/blog/2026/10/29/karyn-kusama-to-direct-mouthwashing-movie-for-sony-the-invitation-writers-to-pen-script?ref=killscreen.com), both citing The Hollywood Reporter, say the script will come from Matt Manfredi and Phil Hay, who wrote Kusama's *The Invitation* (2015) and *Destroyer* (2018). Scott Derrickson, director of *Sinister* and *The Black Phone*, is producing. Kusama also directed *Girlfight* and *Jennifer's Body* and has worked mostly in television since *Destroyer*, including as an executive producer on *Yellowjackets*.

*Mouthwashing* follows the five-person crew of the freighter Tulpar after it crashes and strands them in deep space. It is played in first person, with low-polygon characters in the style of the original PlayStation, and it tells its story out of order, cutting between the days before and after the crash. As food runs out, the game turns into a study of responsibility, denial and the abuse of power among people who cannot leave.

The deal lands at a busy moment for the game. *Mouthwashing* arrived on Nintendo Switch, PlayStation 5, Xbox Series X/S and Xbox Game Pass the same day, and Screen Gems released Zach Cregger's *Resident Evil* adaptation earlier this fall. Wrong Organ is meanwhile building its next horror game, [*Carcass Clad*](https://www.killscreen.com/a-tank-with-no-interface-is-wrong-organs-next-horror/), a three-player tank with no onscreen interface. The original game remains on [Steam](https://store.steampowered.com/app/2475490/Mouthwashing/?ref=killscreen.com).
