Hogfather(2007)

It's the night before Hogswatch, usually a time of joy on Discworld, but there are suspicious going-on and the criminal underworld is abuzz. The beloved Hogfather - the jolly bearer of glee and pork-related gifts for children everywhere - has vanished. Suddenly, Discworld's entire mythical system is under threat. The fate of this magical time rests in the hands of a very motley group: A band of wizards headed up by a mystical university president named Mustrum Ridcully (Joss Ackland), a loyal manservant called Albert (David Jason), a level-headed governess called Susan Sto Heilt (Michelle Dockery), and her grandfather, who happens to be - Death (Marnix van den Broeke).
