Sony adapts Mouthwashing with Kusama attached to direct

Sony Pictures has acquired film rights to indie horror game Mouthwashing, attaching Karyn Kusama to direct and experienced horror producers. The news gives content operators a new fan conversation and platform window.

What happened

Sony Pictures Entertainment has acquired the film rights to indie horror game Mouthwashing from developer Wrong Organ, according to The Hollywood Reporter. Karyn Kusama, director of Jennifer's Body and The Invitation, is attached to direct. The screenplay will be written by Matt Manfredi and Phil Hay, the screenwriters behind The Invitation, and Scott Derrickson, director of The Black Phone and Sinister, is producing.

The project does not yet have a release date. Sony is likely hoping the combination of horror talent and hit video game IP will repeat the success it saw with Resident Evil. Zach Cregger's adaptation of Capcom's survival horror series was not only a critical hit, but also a financial success. Mouthwashing itself launched on PC in 2024, and as of today it is also available on Nintendo Switch, PlayStation 5, Xbox Series X/S and through Xbox Game Pass.

The game follows the crew of a stranded spaceship as they slowly lose their grip on reality. It is not chock-full of jump scares, but its heavy themes and surreal imagery make it an interesting choice for a film adaptation.

Key facts

• Sony Pictures Entertainment acquired the film rights from developer Wrong Organ, according to The Hollywood Reporter.
• Karyn Kusama is attached to direct; the writers are Matt Manfredi and Phil Hay; Scott Derrickson is producing.
• Kusama previously directed Jennifer's Body and The Invitation; Derrickson directed The Black Phone and Sinister.
• Mouthwashing launched on PC in 2024 and is now available on Nintendo Switch, PlayStation 5, Xbox Series X/S and Xbox Game Pass.
• No release date has been announced for the film.

Our analysis

The announcement matters because it shows how a viral indie game can move into studio adaptation without being a decades-old franchise. The source frames the move through Sony's recent history with Resident Evil, noting that Zach Cregger's adaptation was both a critical hit and a financial success. That comparison suggests a repeatable model: pair established horror filmmakers with an IP that already has a distinct tone and built-in audience. For creators, the key signal is that Mouthwashing's appeal is described as grounded, thematic and surreal rather than reliant on jump scares—so atmosphere and story identity can be enough to attract adaptation interest.

The timing also links the film news to a wider availability push. Mouthwashing launched on PC in 2024 and is now on current-generation consoles and Xbox Game Pass. This likely creates a fresh entry point for new players who hear about the film and want to experience the story first. Because no release date is set, community managers have a long content runway, but the talent attachments give immediate, concrete material to discuss. The risk is expectation mismatch: fans of Resident Evil's more goofy horror may need to be prepared for a slower, heavier adaptation, and operators can frame that difference early.

For brand marketers, this is an example of transmedia IP building around an indie title. It suggests smaller games with strong visual and thematic identities can become partnership or content subjects well before a film release, especially when the game is widely accessible on subscription services.

What it means for operators

• Use the announcement and talent names as an immediate content hook; discuss Kusama, Manfredi, Hay and Derrickson's past work to keep horror and gaming communities engaged without waiting for a trailer.
• Plan game coverage around the current platform availability—PC, Nintendo Switch, PlayStation 5, Xbox Series X/S and Xbox Game Pass—so viewers can play the story before the film arrives.
• Frame content around the game's grounded, psychological and surreal tone rather than jump scares; this aligns with the source description and can attract audiences who avoid traditional horror spectacle.
• Track Sony's Resident Evil comparison as a fan-sentiment signal, but avoid repeating financial claims; instead use the adaptation announcement to discuss how indie IP and established horror talent are being packaged.
