Fry, dressed in a dapper suit, declares his special treat is: "A little mince. Well it's only once a year."
Absolutely Fabulous stars Saunders and Lumley are seen larking around in a kitchen, saying their top festive pastime is: "Stuffing... your face, sweetie."
Ashes To Ashes actor Philip Glenister, who also appears, cheekily says he enjoys: "That girl prancing around in her underwear", referring to skimpily-dressed regular of the adverts, model Noemie Lenoir.
James Nesbitt, Twiggy and Wallace and Gromit also feature among the well-known faces in the campaign, which gets under way on November 11.
For the first time this year, there will be several different adverts running through the festive period, including one starring Wallace and Gromit whose Christmas wish list features cheese.
