"I can't wait for everyone to see my movie in December," Hill said.
"It's full of all the traditional festive family fun - evil twins, brains with legs, giant hamsters and chickens with guns."
The film centres around Hill and his Nan (Walters) who go off on a road trip to Blackpool when they discover that their hamster is seriously ill.
The Harry Hill Movie is directed by Steve Bendelack from a script by Hill, Jon Foster and James Lamont.
Director of photography is Baz Irvine and the film is produced by Robert Jones and Lucky Features and distributed by Entertainment Film Distributors.
