Constantin Films is in development for ‘Infernal Devices’, an adaptation of the spin-off book series written by Mortal Instruments author Cassandra Clare.
Young adult franchise hopeful The Mortal Instruments: City of Bones doesn’t open until August 23, but Constantin Films is already working on a prequel.
The company has thrown into development Infernal Devices, an adaptation of the spin-off book series written by Mortal Instruments author Cassandra Clare, and has hired Stephanie Sanditz to write the screenplay.
Infernal Devices is set in Victorian England and sees a new teen girl plunged into a journey of adventure and self-discovery. The books feature the ancestors of many Mortal Instruments characters as well as some character overlap.
Three books, titled Clockwork Angel, Clockwork Prince and Clockwork Princess, have been published.
Constantin is also on the hunt for a director to bring on Infernal Devices.
The company has a certain amount of faith in the power of Clare and her works. While not at the level of a Stephenie Meyer or Suzanne Collins, the author has a legion of devoted followers, mostly teen girls, the same demographic that has helped power other YA franchises.
