Mouser Brings a Talking Cat and a Fractured Reality to VOD This July

Breaking Glass Pictures has announced the upcoming release of Mouser, a psychological horror feature that promises a surreal descent into paranoia, hallucination, and psychological collapse when it arrives on VOD platforms July 14.

Written and directed by Mary Gallagher, Mouser follows Eleanor (Romina Valenti), a mentally unstable young woman whose grip on reality begins to crumble after a night out triggers a disturbing psychological spiral. As her condition worsens, she finds herself haunted by increasingly vivid encounters with a sinister talking cat named Mouser, a mysterious presence that may be manipulating her actions or simply manifesting from the darkest corners of her fractured mind.

As Eleanor’s world begins to unravel, the distinction between reality and hallucination becomes impossible to determine. What starts as unsettling visions quickly escalates into a terrifying journey through paranoia, violence, and psychological dread, leaving both Eleanor and the audience questioning what can actually be trusted.

The newly announced horror feature appears to lean heavily into surrealism and dream logic, using its central feline antagonist as a gateway into a much larger story about trauma, fear, and the human psyche. Rather than relying solely on traditional horror tropes, Mouser explores the terrifying possibility that the greatest threats may originate from within.

“I wanted to explore how fear and unresolved trauma can influence our choices,” Gallagher said in a statement. “Mouser suggests that our greatest struggles are often internal, and I hope audiences leave questioning how fear can distort and control our lives.”

The film stars Romina Valenti alongside Gavin O’Fearraigh, Stephen Moeller as the voice of Mouser, Michel Biel, Anastasia Lutz, Emma Cat, Maria Abreu, Chris Fisher, David Singleton, and Eugene Gallagher.

Breaking Glass Pictures CEO Rich Wolff praised the project as an example of the type of ambitious independent genre filmmaking the distributor continues to support.

“Mouser is exactly the kind of bold, unsettling independent filmmaking we champion at Breaking Glass Pictures,” Wolff said. “Mary Gallagher delivers a fearless psychological horror experience that pulls audiences deep into a fractured reality and doesn’t let go.”

The film has already generated attention on the festival circuit. Mouser was selected for the Indie Vegas Film Festival and earned the award for Best Original Screenplay (Feature Film) at the Marina del Rey Film Festival. The production also recently celebrated a red carpet screening at the Lumiere Theater in Beverly Hills, where it reportedly received a strong audience response ahead of its wider release.

For horror fans who appreciate psychological uncertainty, unreliable realities, and surreal nightmares, Mouser looks positioned to deliver a deeply unsettling experience that prioritizes atmosphere and mental anguish over conventional scares.

Whether Mouser is a supernatural force, a manifestation of trauma, or something even stranger remains to be seen, but one thing is clear from the film’s premise: Eleanor’s nightmare is only just beginning.

Mouser arrives July 14, 2026, on Amazon, Fandango, Dish, iNDEMAND, and additional VOD platforms from Breaking Glass Pictures.
