Mouthwashing Live-Action Movie: Jennifer’s Body Director Karyn Kusama Boards Hit Indie Horror Adaptation

The acclaimed indie horror game Mouthwashing is being adapted into a live-action feature film, with Karyn Kusama—director of cult classic Jennifer’s Body—attached to helm the project. Developed by Wrong Organ and released in 2024, Mouthwashing earned widespread praise for its unsettling atmosphere, nonlinear narrative, and psychological depth, quickly becoming a standout in the indie horror scene. The announcement marks a significant step for the game’s growing franchise, bringing its claustrophobic, dread-soaked story to a broader audience. Kusama’s involvement signals a serious commitment to preserving the game’s distinctive tone, given her track record with genre-bending horror and character-driven tension. The adaptation is expected to draw both gaming and horror communities, with fans eager to see how the game’s first-person perspective and fragmented storytelling translate to film. While details on casting and release date remain under wraps, the collaboration between a rising indie studio and an established genre director underscores Hollywood’s increasing appetite for video game horror IP. Mouthwashing’s move to the big screen could set a new benchmark for how small-scale, narrative-focused games are adapted for cinema.
