Sony Announces Film Adaptation of Indie Horror Game 'Mouthwashing'

Sony Secures Rights to 'Mouthwashing'

Sony Pictures Entertainment has acquired the film rights to the indie horror title Mouthwashing from developer Wrong Organ, according to The Hollywood Reporter. The deal positions Sony to leverage a growing trend of video‑game‑to‑screen adaptations, aiming to replicate the franchise success seen with Resident Evil.

Directorial Team Attached

Karyn Kusama, known for directing Jennifer's Body and The Invitation, is set to helm the adaptation. The screenplay will be penned by Matt Manfredi and Phil Hay, the writers behind The Invitation. Production will be overseen by Scott Derrickson, director of The Black Phone and Sinister. The involvement of these horror‑focused creators suggests Sony intends to emphasize the game’s atmospheric storytelling over traditional jump‑ scares.

Game Overview and Tone

Mouthwashing follows a crew stranded on a spaceship as they gradually lose their grip on reality. The title is described as more grounded and thematically heavy than the often‑playful horror of Resident Evil. Its surreal imagery and psychological themes make it a distinctive candidate for a cinematic retelling. The game launched on PC in 2024 and has since expanded to Nintendo Switch, PlayStation 5, Xbox Series X/S, and is available via Xbox Game Pass, giving a broad audience access to the source material.

Potential Impact and Comparisons

The move reflects a broader industry shift toward adapting indie video‑game properties, which can offer fresh narratives and lower acquisition costs compared to established franchises. Sony’s Resident Evil films have proven both critical and commercial successes, blending high‑budget action with the series’ signature survival‑horror elements. While Mouthwashing lacks the same recognizable brand equity, its distinct atmosphere could appeal to audiences seeking more introspective horror experiences.

From a practical standpoint, the film could serve as a pilot for a potential franchise, especially if the first installment performs well. However, the market remains uncertain: recent live‑action adaptations of lesser‑known games have struggled to find a balance between fidelity to the source and mainstream appeal. The success will likely depend on how well the screenplay translates the game’s surreal, psychological tension to the screen.

What Remains Unknown

Key details are still pending. No release date has been announced, and casting choices have not been disclosed. The extent to which the film will retain the game’s specific plot points, character arcs, or thematic elements is also unclear. Additionally, the budget and any potential streaming versus theatrical distribution strategy have not been revealed.
