A movie version of Terry Pratchett's Discworld novel Hogfather is being filmed right now in the UK, for broadcast at the end of this year. It will be broadcast, as a four-hour mini-series, on Sky One in the UK and the Hallmark Channel in the USA.

Update, Dec 4 @ 11:00 -- The US broadcast of Hogfather seems to have fallen through for this year (though I have heard that it's likely it will show up in December of 2007), but those of us on the Pratchett-benighted side of the Atlantic can still check out Sky One's Hogfather website, which will start a "Twelve Days of Hogwatch" countdown tomorrow, December 5th.
