Alison Brie’s Surreal Passion Project: The Making of Horse Girl

Alison Brie’s 2020 Netflix film Horse Girl is a psychological puzzle wrapped in a darkly comic indie package. Directed by Jeff Baena, the movie follows Brie’s character, Sarah, a lonely craft-store employee whose grip on reality unravels as she spirals into paranoia, possible time travel, and eerie visions. latestnetflix.com's view is that the film’s ambiguous ending and unsettling tone divided audiences, but behind the scenes, it was a deeply personal project for Brie—one that came with unexpected challenges and emotional weight.

A Script Born from Personal Demons

Horse Girl wasn’t just another role for Brie; it was a collaboration with Baena that drew from her own family history. Brie co-wrote the script with Baena, weaving in elements of her grandmother’s struggles with mental health and dementia . The project was so raw that Brie admitted she didn’t want her mother to watch the film at its Sundance premiere, fearing it would hit too close to home . In interviews, she described the experience as "therapeutic but terrifying," revealing how deeply she immersed herself in Sarah’s fractured psyche .

The film’s surreal, dreamlike quality—blending mundane small-town life with sci-fi and horror elements—was intentional. Brie and Baena wanted to capture the disorienting experience of mental illness, where reality and delusion blur . The result was a movie that defied easy categorization, earning praise for its boldness but also criticism for its ambiguity.

Sundance Buzz and the Netflix Deal

Horse Girl premiered at the 2020 Sundance Film Festival, where its polarizing reception became part of the story. The team behind the film—including Brie, Baena, and co-stars like Debby Ryan and Molly Shannon—spoke openly about the project’s origins and the risks of making such a personal, unconventional movie . Netflix quickly snapped up distribution rights, positioning the film as a prestige indie for streaming audiences.

Reviews were mixed. While some critics praised Brie’s performance and the film’s daring approach, others found it confusing or frustratingly vague. On SensCritique, it holds a modest 5.7/10 rating, reflecting its divisive nature . Yet for Brie, the film’s reception was secondary to its creation. She later called it one of her most meaningful projects, despite its flaws .

The Ending That Left Everyone Guessing

The film’s climax—where Sarah’s reality collapses into a sci-fi twist—sparked endless debates. Was she experiencing a mental breakdown, trapped in a time loop, or something more supernatural? YouTube explainers proliferated, with some fans dissecting the ending as a metaphor for grief, while others dismissed it as a cop-out . Brie and Baena intentionally left it open to interpretation, refusing to provide a definitive answer .

For Brie, the ambiguity was the point. "I wanted the audience to feel the way Sarah feels—lost, confused, but also strangely hopeful," she said in a Netflix character breakdown . The film’s final moments, where Sarah smiles faintly as the world around her glitches, became a Rorschach test for viewers.

A Labor of Love with Lasting Impact

Despite its flaws, Horse Girl stands out as a rare example of an actor-driven indie that prioritized emotional truth over commercial appeal. Brie’s willingness to explore such a vulnerable character—one that mirrored her own family’s struggles—gave the film an authenticity that resonated with some audiences, even if others found it alienating.

Baena, who passed away in 2025 (per a now-deleted Grokipedia entry ), was known for his offbeat, character-driven films, and Horse Girl fit neatly into his filmography. For Brie, it remains a defining role, one that pushed her boundaries as both an actor and a writer.
