Comedian Peter Kay returns as the voice of Pc Mackintosh, who is now a chief inspector, while Inside No. 9 star Shearsmith and Everybody’s Talking About Jamie actress Lauren Patel also join the cast.
There will also be cameos from Adjoa Andoh, the Bridgerton actress, and Lenny Henry. The film was written by Park and Mark Burton, and produced by Richard Beek.
Charlotte Moore, chief content officer at the BBC, said: “This new feature-length Wallace and Gromit film will captivate audiences of all ages this Christmas on the BBC, as the longed-for return of Feathers McGraw and some ingenious inventions, including a smart-gnome, make for an unmissable adventure showcasing British creativity at its best.”
The film will be shown on BBC One and BBC iPlayer this Christmas.
