New Film Set for September Release
“Shaun the Sheep: The Beast of Mossy Bottom,” the third feature in the Shaun the Sheep franchise, will open in U.S. theaters on Friday, September 18 and simultaneously in the United Kingdom through Sky Cinema. The film will later receive a home-entertainment release later in the year. Internationally, StudioCanal handles theatrical distribution in territories including France, Germany, Australia, New Zealand, Poland, Benelux and Italy.
Behind-the-Scenes Poster Reveal
GKIDS posted a four-minute making-of video on its YouTube channel that walks viewers through the conception and construction of the film’s vintage-horror-inspired poster. The artwork shows Shaun in a lab coat and goggles brewing a potion, a visual nod to classic Hammer and Universal horror films. The clip features Aardman staff discussing the process, highlighting the studio’s handcrafted stop-motion aesthetic.
Key Creative Personnel
The film marks the feature-directorial debut of longtime Aardman collaborators Steve Cox and Matthew Walker. It is written by Mark Burton (screenwriter of *Wallace & Gromit: The Curse of the Were-Rabbit* and *Shaun the Sheep Movie*) with co-writer Giles Pilbrow (writer on *Shaun the Sheep: Adventures from Mossy Bottom* and *The Flight Before Christmas*). Voice talent includes Justin Fletcher as Shaun, joined by John Sparkes and Kate Harbour.
The behind-the-scenes feature also includes animation director Claire Rolls, photographer Richard Davies, director of photography Charles Copping, puppets team leader Will Harding, and GKIDS design manager Cynthia Sega (or Cynthia Segal, see note below).
Aardman’s Milestone and Franchise History
The release arrives during Aardman Animations’ 50th anniversary, a year of events celebrating the studio’s legacy of meticulous stop-motion craft. The franchise previously delivered the Academy-Award-nominated *Shaun the Sheep Movie* (2015) and *A Shaun the Sheep Movie: Farmageddon* (2020), following earlier successes such as the *Wallace & Gromit* shorts that earned multiple Oscars.
