Set in a bakery, the stop-motion, clay animation short will be called "Trouble at' Mill," creator Nick Park said.
The film will mark a return to the format of Aardman Animations' award-winning 30-minute movies, "A Close Shave" and "The Wrong Trousers," which, like "Mill," were written by Bob Baker.
Inventor Wallace and his trusty dog, Gromit, were last seen in the full-length, big-screen adventure "Curse of the Were-Rabbit," which won Best Animated Feature Academy award in 2006.
"I love making films for the cinema but the production of 'Chicken Run' and 'Curse of the Were-Rabbit' were virtually back to back and each film took five years to complete," Park said.
"'Trouble at' Mill' will be so much quicker to make and I can't wait to get back into production."
The film is in pre-production but clips can be seen on the Wallace and Gromit Web site -- http://www.wallaceandgromit.com/.
