The Hollywood Reporter has reported that Constantin Film has moved forward on development of The Infernal Devices: Clockwork Angel adaptation and that Stephanie Sanditz will be penning the script.
They have also reported that the search for a director is underway.
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.
Mortal Instruments, a best-selling series of fantasy romance books, centers on a young girl who discovers she is part of a hidden race of angels known as Shadowhunters locked in a battle with warlocks and vampires called Downworlders.
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 Mortal Instruments: City of Bones isn’t set to hit theaters until Aug. 23, but Constantin Film is already hard at work on the prequel series. It shows they have a lot of confidence in the Mortal Instruments film franchise.
The Mortal Instruments: City of Ashes and The Mortal Instruments: City of Glass, the sequels to City of Bones, would film back-to-back if green-lit. If The Infernal Devices: Clockwork Angel is green-lit it would most likely be released after those two, but could start production soon after.
