The official trailer for The Sheep Detectives has arrived, setting the stage for a charmingly offbeat family mystery arriving in theaters this May. The film adapts Leonie Swann’s 2005 novel Three Bags Full into a live-action and animated comedy about a flock of sheep who turn detective after their beloved shepherd is killed.
Directed by Kyle Balda and written by Craig Mazin, the project has been in development for nearly a decade. Mazin was reportedly "enchanted by how smart, moving and philosophical" the source material was, though securing the rights proved a lengthy process. The film’s journey to the screen included a title change from Three Bags Full: A Sheep Detective Movie and several shifts in its release date before landing on its current May 2026 slot.
Who’s in the cast?
The human ensemble is led by Hugh Jackman as George Hardy, the shepherd whose murder kicks off the plot. Nicholas Braun plays Tim Derry, the village’s clumsy police officer, while Nicholas Galitzine appears as the suspicious journalist "Elliot Matthews." Molly Gordon stars as George’s daughter Rebecca Hampstead, with supporting roles filled by Hong Chau, Emma Thompson, Tosin Cole, and Kobna Holdbrook-Smith.
The real stars, however, are the sheep. Julia Louis-Dreyfus voices Lily, the intelligent Shetland ewe who leads the investigation. Bryan Cranston is Sebastian, a brooding former prize-fighter sheep, and Chris O’Dowd plays Mopple, the flock’s resident memory keeper. The impressive voice cast also includes Regina Hall, Patrick Stewart, Bella Ramsey, and Brett Goldstein as twin rams Reggie and Ronnie.
What is the story about?
The story unfolds in the English village of Denbrook. Shepherd George Hardy spends his evenings reading murder mysteries to his oblivious flock. The sheep live in a blissful state of denial about mortality, believing death is only fiction. When George is found dead with his hands stained blue and green, the sheep are devastated. They decide to solve the crime themselves, diving into a world of human suspects, hidden wills, and family secrets.
Their investigation reveals George was a secret millionaire, having invented a valuable blue medicine. Suspects include his newly arrived daughter, a mysterious twin son, the local butcher, and a neighboring shepherd. The film balances its cozy mystery with surprisingly profound themes about grief, memory, and community. As critic Sam Adams noted for Slate, the sheep are "trying to understand isn't who killed George but what it means that he's dead."
How has it been received?
Early critical reaction has been overwhelmingly positive. The film holds a 95% fresh rating on Rotten Tomatoes based on 194 reviews. The critical consensus calls it "drolly funny and sweet as a lamb" and "a delightful family entertainment." Audiences have responded warmly too, giving the film an "A–" CinemaScore.
Reviewers have singled out the voice cast and the film's emotional depth. Empire’s Harry Stainer praised the "abundance of pathos," helped by "Julia Louis-Dreyfus' Lily, Chris O'Dowd's soulful Mopple, and Bella Ramsey's high-energy, question-asking lamb." The film has also performed solidly at the box office, grossing $126 million worldwide as of June 2026.
When and where can you watch it?
The Sheep Detectives opened in theaters on May 8, 2026, following special preview screenings on May 2. It was released by Amazon MGM Studios in the United States. The film became available for home viewing on Amazon Prime Video starting June 24, 2026.
