Sir Terry Pratchett has launched an independent TV production company, Narrativia, with exclusive global multimedia rights to the author's bestselling works.
Narrativia will produce TV adaptations of some of Pratchett's best-known novels, including a four-part series based on his 1990s comedy Good Omens.
The London-based production firm will be led by managing director Rod Brown alongside Pratchett's daughter and fellow writer, Rhianna Pratchett, and his business manager, Rob Wilkins.
Pratchett said: "This is an exciting and natural development for me and my works, and I look forward to working closely with the team to develop new stories in areas other than just print and ebooks and, of course, seeing my first big-screen project come to fruition."
Narrativia is in the process of producing a 13-part series set in Ankh Morpork, the fictional city from Pratchett's Discworld novels, named The Watch, after the city's police force.
Good Omens will be co-written by Monty Python star Terry Jones and Gavin Scott, whose credits include The Mists of Avalon and Legend of Earthsea. The Watch will be written by Guy Burt, whose credits include The Borgias and The Bletchley Circle.
