'The Iron Trial' centers on boy magician

BERLIN — Constantin Film has acquired rights to a new fantasy book series to be written by bestselling scribes Cassandra Clare (“The Mortal Instruments”) and Holly Black (“The Spiderwick Chronicles”).

Clare and Black are collaborating for the first time on “The Iron Trial,” book one of the planned series about the adventures of a 12-year-old boy magician.

Clare and Black will adapt the screenplay and serve as executive producers.

The deal follows Constantin and Unique Features’ adaptation of “The Mortal Instruments,” which is set to shoot this summer. “The Mortal Instruments,” based on the first book of the series “City of Bones,” will be directed by Harald Zwart and star Lily Collins and Jamie Campbell-Bower, with Kulzer and Unique’s Bob Shaye and Michael Lynne producing, and Martin Moszkowicz, Constantin’s head of film and TV, exec producing. “The Mortal Instruments” will begin shooting in Toronto in August.

Clare’s books have sold more than 10 million copies worldwide and have been translated into 34 languages.

“The Mortal Instruments” book franchise comprises six books, including the forthcoming “City of Lost Souls” and “City of Heavenly Fire” as well as a series of prequels and sequels entitled “The Infernal Devices” and “The Dark Artifices,” respectively.

Black is best known for the best-selling “The Spiderwick Chronicles” series, which includes 11 books and spawned the 2008 film of the same name. Black’s books have likewise sold more than 10 million copies around the globe.
