Shaun the Sheep returns with a Halloween mix-up in The Beast of Mossy Bottom
Shaun the Sheep returns to cinemas on 18 September with The Beast of Mossy Bottom, his third film outing.
The 1 hour 20 minute feature is made in stop-motion, with models moved a fraction at a time between frames, by Aardman Animation, according to details listed by The Hollywood Reporter. Aardman has dated the UK and US cinema release to 18 September 2026, as noted by Aardman.
Shaun began as a side character in Aardman’s Wallace & Gromit series before getting his own films. The two earlier cinema outings were 2015’s Shaun the Sheep Movie and 2019’s A Shaun the Sheep Movie: Farmageddon, as listed by The Hollywood Reporter.
The new story runs up to the Halloween Hoedown. The farmer and the flock are getting ready for the event when the farmer accidentally wrecks their pumpkin patch. Shaun tries to fix it with an experiment. It goes wrong.
The experiment tips the farmer’s hair-growth lotion over him. He ends up covered head to toe in thick, matted orange fur. No one on the farm knows it is him.
That sets up the mix-up. A new arrival, the local veterinarian, is tracking a creature she calls the Beast of Mossy Bottom. She believes it is Bigfoot, the large ape-like figure from North American folklore, according to The Hollywood Reporter. Around the village, talk turns to altered food and pitchfork-wielding locals join the hunt, as described by The Guardian.
Justin Fletcher voices Shaun. John Sparkes voices two roles, the farmer and Bitzer, the farmer’s canine helper.
Nina Sosanya voices the veterinarian. The listed cast also includes Kate Harbour, Dani Dyer, Roman Kemp and Paul Whitehouse. The film is directed by Steve Cox and Matthew Walker and written by Mark Burton and Giles Pilbrow.
In the US, the film is being released by GKIDS, a distributor known for animation, as reported by The Hollywood Reporter. Aardman developed the project with Sky and Studiocanal, which revealed a first look in October 2025. Promotion has included two trailers and, in Britain, a giant sheep-themed tapestry finished with a final stitch by Olympian Tom Daley.
For families, this means a short cinema trip. Eighty minutes. No dialogue to follow, just voices, bleats and visual gags.
