Cult Horror Hit Mouthwashing Is Being Adapted Into a Live-Action Film

October 29, 2026 - 22:37

The unsettling indie horror game Mouthwashing is making the leap from screens to cinema. A live-action feature film adaptation is officially in the works, with Karyn Kusama, the director known for Jennifer's Body, set to helm the project.

Mouthwashing first gained attention for its psychological storytelling and grim atmosphere. The game takes place aboard a stranded cargo ship, where a crew of five faces dwindling supplies and mounting tension. Its narrative structure and disturbing imagery helped it build a dedicated following online, turning it into one of the more talked-about indie horror releases in recent memory.

Details about the film's cast, release window, and production timeline remain under wraps for now. The involvement of Kusama suggests the adaptation will lean into the game's character-driven dread rather than relying on jump scares alone. Her past work has shown a knack for blending horror with sharp social commentary, which fits the source material's tone.

Fans of the game have responded with a mix of excitement and caution, as video game adaptations continue to be a tricky proposition. Still, the combination of a cult favorite property and an established director has generated real momentum. More information is expected as the project moves further into development.
