The Mouse movie begins with a friendship that feels unbreakable, and then it breaks it. Set in Little Rock, Arkansas in 2002, this quiet American coming-of-age drama follows Minnie Dunn, a shy high-school student who has spent her life in the shadow of her charismatic best friend Callie Bell. When Callie dies suddenly in an accident, Minnie is left rudderless at the start of the summer before their senior year, searching for an identity of her own. The Mouse movie arrives in limited theatres in the United States on 6 November 2026, before expanding wider on 13 November, and it is already one of the most warmly reviewed small films of the year.

What makes the Mouse movie stand out in a November crowded with blockbusters is its refusal to rush grief. Directors Kelly O’Sullivan and Alex Thompson, the duo behind Saint Frances and the acclaimed 2024 drama Ghostlight, tell the story at the pace of real mourning: awkward silences, half-finished sentences, and small kindnesses that arrive when they are least expected. The result is a film that festival audiences have described as quietly devastating, and also, unexpectedly, full of humour and warmth.
The loss at the centre of the Mouse movie
Minnie, played by Katherine Mallen Kupferer, is good at maths and awkward at almost everything else. Her best friend Callie, played by Chloe Coleman, is the opposite: outgoing, determined, and dreaming of a big life. Minnie herself admits she thinks she is going to have a small one. That contrast is the engine of the Mouse movie. The two girls are inseparable until tragedy separates them, and the film is really about what happens to the person left behind.
After Callie’s death, Minnie drifts. She does not know who she is without her best friend, and the film never pretends there is a quick answer. Instead, it watches her try things on: a new friendship, a new creative outlet, a new way of being in the world. The Mouse movie treats that slow, uncertain process with rare honesty. There is no big speech that fixes everything, and no villain to blame. There is just a teenager learning, day by day, how to carry a loss that will not go away.
Two mothers, one grief
The most surprising relationship in the Mouse movie is not between two teenagers at all. It is between Minnie and Helen Bell, Callie’s mother, played by Oscar nominee Sophie Okonedo. Helen is a former classical pianist, poised and grieving, and she begins training Minnie to perform at a school cabaret. The lessons give both women something they desperately need: a reason to leave the house, a shared project, and a way to talk about Callie without only talking about the accident.
But the closeness comes at a cost, and the Mouse movie is brave enough to show it. As Minnie grows closer to Helen, she pulls further away from her own mother, Barbara, played by Tara Mallen, Kupferer’s real-life mother. Barbara’s home life is chaotic, and the bond between mother and daughter is already fractured. Watching Minnie find comfort in someone else’s mother while her own mother watches from the sidelines is painful, and it is the film’s most original idea. Grief, the film suggests, does not always bring families together. Sometimes it rearranges them in ways nobody planned.
Okonedo’s performance has drawn particular praise on the festival circuit. She was honoured with the Spotlight Award at the Chicago International Film Festival in October 2026, and critics have called Helen perhaps her finest role. She plays grief not as constant weeping but as composure that keeps cracking at the edges, and her scenes with Kupferer carry the whole film.
The Ghostlight team returns
The Mouse movie reunites O’Sullivan and Thompson with Kupferer and Mallen, who both starred in Ghostlight, and that continuity shows on screen. O’Sullivan wrote the screenplay and co-directed with Thompson, and their approach is the same as in their earlier work: small budgets, real locations, performances that feel overheard rather than performed. The camera stays close, the dialogue sounds like actual teenagers talking, and the emotional beats land because nothing around them is exaggerated.
The supporting cast adds texture without stealing focus. Iman Vellani, known to Marvel fans as Ms. Marvel, plays Kat, a video-store clerk who has also been touched by unimaginable loss, and who forms a tender relationship with Minnie. David Hyde Pierce brings warmth as Mr. Murdaugh, the drama teacher. Beck Nolan also appears in the cast. The score comes from Hamilton Leithauser of The Walkmen, whose music gives the 2002 setting a lived-in, slightly frayed feeling that suits the story perfectly.
From Berlin to Chicago: a festival journey
The Mouse movie premiered in the Panorama section of the Berlin International Film Festival on 13 February 2026, where it finished as second runner-up for the Panorama Audience Award. That early response set the tone for everything that followed. It went on to play as the Centerpiece film of the 62nd Chicago International Film Festival, a homecoming of sorts for its Chicago-based directors, and it has continued to build word of mouth at festivals through the autumn, including NewFest in October 2026.
Festival reviews have consistently used the same words: moving, powerful, honest. One early review called it a film of the highest calibre, praising how it handles loss, grief and new beginnings without ever turning sentimental. That reputation is exactly why a small drama like this can find an audience in November. People do not go to it for spectacle. They go because someone they trust told them it made them cry, and then made them feel better.
Mouse movie release date and where to watch
The Mouse movie opens in limited theatres in the United States on 6 November 2026, released by Independent Film Company and Sapan Studio, and it expands to a wider release on 13 November 2026. That staggered rollout is typical for an independent film of this size: it opens where the buzz is strongest, then grows if audiences respond.
There is no OTT or streaming date announced yet, and no streaming platform has been named. That is normal for a theatrical-first independent release at this stage. Any streaming announcement will come after the cinema run, so for now the only way to watch the Mouse movie is on the big screen. Viewers outside the United States should check local listings, as international dates may differ from the American rollout.
