Aardman Announces Third Shaun the Sheep Stop-Motion Film for September Release

The film features a voice cast including Justin Fletcher as Shaun and Timmy, John Sparkes as the Farmer and Bitzer, Kate Harbour as Timmy’s Mum, Nina Sosanya as the Vet, Dani Dyer as an Influencer, Roman Kemp as a Pizza Boy and Paul Whitehouse as a Shopkeeper.
The Farmer’s transformation is caused when some of Shaun’s experimental formula gets into the Farmer’s hair-restoration tonic, turning him into a fur-covered creature compared by the review to “Bigfoot crossed with Cousin Itt.”
Beyond the farm and barn laboratory, the stop-motion production visits settings including the rural countryside, ocean freighters and the deep sea, with detailed physical sets helping each location feel distinct and lived-in.
The story’s humor draws on silent-comedy traditions associated with Charlie Chaplin, Buster Keaton and Harold Lloyd, as well as classic Looney Tunes and Disney shorts; the review says the film favors warmth over heavy-handed moral lessons.
The production was completed on Aardman’s tightest schedule yet, according to the filmmakers, who said their prior work as animators, story artists and episodic directors gave them an unusually deep familiarity with Shaun’s character and world.
Aardman's third Shaun the Sheep feature arrives September 18, 2026, with a Halloween-themed adventure that sends the dialogue-free sheep into mad science gone wrong. Titled "Shaun the Sheep: The Beast of Mossy Bottom," the stop-motion film follows Shaun as he attempts to regrow the flock's destroyed pumpkin patch using an experimental formula—but the concoction transforms the Farmer into a hairy creature and sparks chaos in the countryside. GKIDS will release the 80-minute comedy in U.S. theaters, bringing the franchise's signature blend of silent-comedy humor and handcrafted animation to family audiences.
The film's central conflict begins when the Farmer discovers Shaun's quick-grow formula and mixes it into his hair-restoration tonic. The combination transforms him into a fur-covered creature—described as "Bigfoot crossed with Cousin Itt." Variety reports that directors Steve Cox and Matthew Walker drew inspiration from Universal Monsters and Hammer Horror movies to craft the spooky setup. The mishap forces Shaun and his flock to investigate the mystery while the Farmer roams the woods as an unrecognizable beast.
The production moves far beyond the farm and barn laboratory. Stop-motion sets take viewers to the rural countryside, ocean freighters, and the deep sea—each location hand-built with distinct details that make them feel lived-in and real. San Diego Reader notes that the filmmakers relied on their backgrounds as animators and story artists to deepen their familiarity with Shaun's world. The team completed the project on Aardman's tightest schedule yet, pulling from their experience with episodic television to streamline production.
The film's humor channels Charlie Chaplin, Buster Keaton, and Harold Lloyd—silent-comedy masters whose work emphasized physical gags over dialogue. Yahoo reports that the 80-minute comedy balances spooky elements with warmth, avoiding heavy-handed moral lessons in favor of genuine laughs. Visual storytelling and handcrafted animation carry the narrative, making the film accessible to audiences of all ages. The voice cast includes Justin Fletcher as Shaun, John Sparkes as the Farmer, and appearances by Nina Sosanya, Dani Dyer, and Roman Kemp.
