Shaun the Sheep and his flock are back for a Halloween adventure in Shaun the Sheep: The Beast of Mossy Bottom. The 80-minute stop-motion comedy follows the animals as they prepare for Halloween, only for their carefully grown pumpkin patch to be destroyed by the Farmer.
Shaun decides to become a mad scientist and create a potion to replace the pumpkins. Unfortunately, the glowing pink concoction ends up being used as a hair tonic, transforming the Farmer into a hairy creature that has the residents of Mossingham convinced a monster is on the loose.
The third theatrical Shaun the Sheep movie arrives in cinemas in the United States and United Kingdom on September 18, 2026, just in time for Halloween movie season. The film is also the latest adventure for characters who first appeared in Wallace & Gromit: A Close Shave in 1995.
Inside the Making of The Beast of Mossy Bottom
The Beast of Mossy Bottom marks the feature directorial debut of longtime Aardman collaborators Steve Cox and Matthew Walker. Mark Burton, who worked on The Curse of the Were-Rabbit and previous Shaun the Sheep films, co-wrote the screenplay with Giles Pilbrow.
Justin Fletcher returns as Shaun and the flock, with John Sparkes voicing the Farmer and Bitzer and Kate Harbour returning as Timmy’s Mum. The cast also includes Nina Sosanya, Paul Whitehouse, Dani Dyer and Roman Kemp.
The production team went to unusual lengths to make the monster’s appearance work in stop-motion. The creature’s orange hair was reinforced with glue and wires so animators could manipulate individual sections, while some visual effects—including the lightning—were deliberately created with a handcrafted appearance.
“We pushed everything further than we’ve ever pushed,” cinematographer Charles Copping said of the production. The filmmakers expanded the world with fog, water, a large forest, a cargo ship and other elements that helped make this Shaun adventure visually bigger than previous projects.
Aardman Continues Its Stop-Motion Legacy
The Beast of Mossy Bottom continues the distinctive stop-motion tradition of Aardman, the British animation studio behind Shaun the Sheep, Wallace & Gromit and Chicken Run. The new movie also marks the third feature centered on Shaun, following The Shaun the Sheep Movie and A Shaun the Sheep Movie: Farmageddon.
The franchise has already proved successful on the big screen. The Shaun the Sheep Movie earned $111 million worldwide, while Farmageddon earned $42 million, and both received Oscar and BAFTA nominations for Best Animated Feature.
The new movie continues Aardman’s tradition of largely wordless storytelling, allowing visual comedy and physical performances to carry the story. ScreenDaily describes the film as a “charming family adventure,” while noting that its Halloween setting brings gentle spooky-season thrills alongside the studio’s familiar humor.
For parents looking for Halloween entertainment that doesn’t rely on intense scares, The Beast of Mossy Bottom offers a combination of monster-movie parody, slapstick comedy and handmade animation. Its theatrical release also gives families a chance to introduce younger viewers to one of animation’s most enduring stop-motion franchises.
