The Sheep Detectives Movie: Everything We Know About Hugh Jackman’s Woolly Whodunnit
Imagine Knives Out, but the detectives have woolly coats, four legs, and a taste for the finest clover in the meadow.
Following the official trailer drop on 18 December 2025, the internet has gone wild for what promises to be the most unique mystery of the decade. Amazon MGM Studios and Sony Pictures have finally lifted the lid on the project formerly known as Three Bags Full, confirming its new title: The Sheep Detectives movie.
If you watched the trailer yesterday, you already know the vibe is chaotic, charming, and distinctly British. But beyond the clips of Hugh Jackman reading to his flock, there is plenty of detail you might have missed.
As a long-time fan of the original “cosy crime” novel, I have dug into the production notes, casting announcements, and filming locations to bring you this comprehensive guide. Here is everything you need to know about the film before it trots into UK cinemas.
The Sheep Detectives Release Date: When is it Hitting UK Cinemas?
Mark your calendars. According to the latest schedule from Sony Pictures Releasing, The Sheep Detectives will arrive exclusively in UK cinemas on 8 May 2026.
This places it squarely as a major Bank Holiday blockbuster contender. The film was originally slated for a slightly earlier window, but the shift to May suggests the studio has massive confidence in its appeal to families and adults alike.
Why the Name Change?
You might remember hearing about this project under the title Three Bags Full. The studio officially rebranded it to The Sheep Detectives in late 2025. From a marketing perspective, it makes sense; it tells the audience exactly what they are getting, a murder mystery solved by livestock, rather than relying on a nursery rhyme reference that might feel too juvenile for a witty PG film.
A “Baa-rilliant” Cast: Who’s Who in the Flock?
The casting for this film is nothing short of spectacular. We have seen ensemble casts before, but rarely one that mixes live-action heavyweights with such a distinct lineup of voice talent.
The Humans: Hugh Jackman & Emma Thompson
Hugh Jackman stars as George Hardy, the unfortunate shepherd whose murder kicks off the plot. In the trailer, we see George isn’t your average farmer; he reads detective novels to his sheep every night, inadvertently training them to solve his own death.
Emma Thompson plays the live-action role of the investigating police officer (or perhaps a local busybody, the trailer keeps her exact role slightly mysterious), bringing her trademark sharp wit to the village setting.
The Sheep Voices: From Julia Louis-Dreyfus to Bryan Cranston
The real stars, however, are the CGI sheep. The production team at Working Title Films has gathered a voice cast that reads like an Emmy Awards guest list.
Identifying which voice belongs to which sheep can be tricky with the fast cuts in the trailer. Here is the breakdown based on the casting sheets:
| Actor | Role | Sheep Personality |
| Julia Louis-Dreyfus | Lily | The de facto leader and smartest ewe in the flock. |
| Bryan Cranston | Sir Ritchfield | The old ram with a hazy memory but immense authority. |
| Nicholas Braun | (Various) | Likely the nervous, younger sheep prone to panic. |
| Nicholas Galitzine | (Various) | Speculated to be one of the more dashing, adventurous rams. |
Plot & Book Origin: From Leonie Swann’s Best-Seller to the Screen
If you haven’t read the source material, you are in for a treat. The film is adapted from the 2005 German novel Glennkill (published as Three Bags Full in the UK) by Leonie Swann.
The book became a cult classic in the UK “cosy mystery” genre. The premise is delightfully absurd: when George is found pinned to the ground with a spade, his sheep decide they are the only ones capable of catching the killer. They know everything about sheep (grazing, breeding, fearing the butcher) and very little about humans, which leads to hilarious misunderstandings about human behaviour.
The Craig Mazin Factor
Here is where things get interesting for film buffs. The screenplay was written by Craig Mazin.
Yes, the same Craig Mazin who wrote the terrifyingly bleak Chernobyl and the emotional powerhouse The Last of Us. Handing a “woolly whodunnit” to a writer known for dark, gritty realism is a stroke of genius. It suggests the script won’t just be slapstick; it will likely have genuine stakes, sharp dialogue, and a tightly woven mystery that respects the audience’s intelligence.
Directed by Kyle Balda (veteran of Minions and Despicable Me 3), the film seems to balance Mazin’s sharp script with vibrant, family-friendly animation.
Spotted on Set: The Sheep Detectives Filming Locations (UK)
While the story is set in the fictional village of Glennkill (originally Ireland in the book, but shifted to England for the film), the production utilised quintessential British countryside locations.
Filming took place throughout the summer of 2024, primarily in Buckinghamshire and Oxfordshire.
Local Experience: Spotting the Scenes
Having spent time hiking near the Chilterns, the backdrops in the trailer are unmistakable. The rolling green hills and stone cottages scream “Midsomer Murders country.”
Specifically, production crews were spotted at White Pond Farm and surrounding villages near Henley-on-Thames. If you are planning a visit to the area, the aesthetic is exactly what you see on screen, ancient hedgerows, narrow lanes, and plenty of actual sheep. It gives the film an authentic texture that a studio backlot simply can’t replicate.
The Official Trailer Breakdown: Key Clues You Missed
The trailer released on 18 December 2025 gave us our first look at the CGI style. It is photorealistic rather than cartoonish, similar to Paddington or Babe.
Key Takeaways:
-
The Soundtrack: The use of The Proclaimers’ “I’m Gonna Be (500 Miles)” sets a distinct tone. It’s energetic, slightly ridiculous, and very British.
-
The Murder Weapon: We see a brief glimpse of a spade. In the book, the position of the spade is a major clue.
-
The Perspective: The camera angles are often low to the ground, mimicking the sheep’s eye view. This cinematography choice is crucial, we only see what the sheep see, which makes the mystery harder to solve.
