Sony has announced a feature film adaptation of Mouthwashing, and I need everyone to stay normal when it comes out.

Background: A Game About Exploitation That Became a Fandom Flashpoint

Mouthwashing is introduced in the source as a video game the writer liked for more than atmosphere. The game is described as having a lot to say about how corporations take advantage of workers. It also plays with character perspective, letting the player in on certain narrative threads while withholding others until they become taut enough to snap. The writer values its length as well: the game is short enough that its misery does not outstay its welcome.

That praise is mixed with wariness. The source says much of the fandom response that came after the game was not enjoyable, and that is why the writer is scared to say Mouthwashing is getting a movie from Sony.

Development: The Rights Move to Sony and the Names Start Arriving

The Hollywood Reporter is cited as the outlet sharing the film-rights news. Sony have acquired the feature film rights to Mouthwashing. The source describes the attached names as both promising and apprehension-inducing.

Scott Derrickson is attached as a producer in part. The writer identifies him as the director of Sinister, which the writer liked well enough, and Doctor Strange, described in the source as "a wet fart sound of a movie." The more interesting creative attachment is Karyn Kusama, director of the excellent cult classic Jennifer's Body, who is attached to direct. The source notes that, given the game's themes of sexual assault, which is putting it lightly, it is nice to see a woman in the director's seat.

The project is linked to Sony Pictures' Screen Gems. A post from Critical Reflex, dated October 29, 2026 at 8:17 PM, says, "YES, MOUTHWASHING MOVIE IS REALLY HAPPENING SOON™". It asks, "You thought you could escape responsibility by turning off your console?" and lists the film as produced by Sony Pictures' Screen Gems and directed by Karyn Kusama.

Writers: A Familiar Collaboration Raises Both Hope and Doubt

The writing attachment is where the source's fear returns. Matt Manfredi and Phil Hay are attached as writers. The pair have long worked together, but the source says they have often worked together on stinkers such as Clash of the Titans, The Tuxedo, and R.I.P.D.

The source balances that concern with a point in their favor. Manfredi, Hay, and Kusama are frequent collaborators, having made The Invitation and Destroyer together. The source also notes that Hay and Kusama are married, which it suggests may help the creative team hold together.

Latest Progress: The Problem Is the Game’s Form and the Fandom’s Reading of It

The broader adaptation worry is not only about Hollywood names. The source says that, as with every single live-action adaptation of a video game, the writer immediately feels it is wholly unnecessary, and certainly thinks that is the case for Mouthwashing.

The game is described as having minimal interactivity, much more of a walking sim than anything else. Yet it also deeply relies on that interactivity, alongside its first-person perspective, so the writer is unsure how well it would translate. Upsettingly, the source says the game developed an uncomfortably intense fandom that frequently treated the game's themes as a suggestion, prioritising skits and memes above a real reckoning with what it is doing. That fandom behavior leaves the writer afraid of a film adaptation.

Current Stage: Mouthwashing Is Moving From Game to Movie, With Uneasy Expectations

At the point the source covers, Mouthwashing has become a film property in motion. Sony have acquired the rights, Screen Gems is attached, Kusama is set to direct, Derrickson is producing in part, and Manfredi and Hay are attached as writers. The October 29, 2026 Critical Reflex post marks the public signal that the movie is happening soon, while the source's own tone remains cautious.

The writer does not deny the game's strengths or the talent now attached to the adaptation. The concern is that a first-person, low-interactivity game about corporate abuse and sexual assault could be flattened by a fandom that treated its themes as material for memes. The current stage is therefore not a simple celebration: a Mouthwashing movie is coming from Sony, but the source leaves the reader with the feeling that the hardest question is whether the film can keep the weight the game tried to place on its players. The source ends with the joke that the writer may log off for the day whenever it comes out.
