Aardman has added Nina Sosanya, Paul Whitehouse and Roman Kemp to the voice cast of "Shaun the Sheep: The Beast of Mossy Bottom", its third stop-motion feature in the Shaun the Sheep franchise, produced with Sky and StudioCanal. The trio joins previously confirmed cast members Dani Dyer and Justin Fletcher, expanding the film's ensemble as it heads towards its cinema release next month.

Sosanya will voice Mossingham's vet, Whitehouse plays the local shopkeeper, and Kemp appears as a pizza boy, while Dyer takes on a social media influencer role in her first-ever animation voice job. The film follows the Mossy Bottom Farm flock as a Halloween pumpkin patch disaster and a missing Farmer spark chaos, directed by Steve Cox and Matthew Walker and written by Mark Burton and Giles Pilbrow. Sky distributes in the UK, StudioCanal handles most other territories and GKIDS covers the US, with the film due in cinemas on 18 September, following 2025's 30th anniversary of Shaun's debut in "A Close Shave".
