Movie: The Colour of Magic (2008) (TV)

Tagline: It's a pigment of your imagination
Trivia: Many of the angry mob of Star People outside Unseen University, and the customers in the Broken Drum during the fight scene, are Discworld fans recruited through fan websites and mailing lists.
Goofs: Revealing mistakes: During the opening title scene, at the docks, several shots show a radio aerial and mast on the side of a building. (Electricity and radio are unknown on the Discworld.)
