Colour of Magic
The BBC live-action production of The Colour of Magic (the original diskworld stories by Terry Pratchett) will get its US television premiere on ION television on November 23 at 7pm ET. The four-hour show will be broadcast in its entirety in the one evening. It stars Shawn Astin (Sam from the Lord of the Rings).
Borders has Hogfather and the animated movies - Soul Music and Wyrd Sisters. I'd seen online that Colour of Magic was also scheduled to appear at Borders earlier in '08, but I have yet to seen it listed as available or on the shelves.
