The Mortal Instruments: City of Bones executive producer Martin Moszkowicz confirmed that a script for The Infernal Devices: Clockwork Angel is underway.

@webreathwords @cassieclare we are working on the screenplay. — Martin Moszkowicz (@mmoszkowicz) March 26, 2013

The Infernal Devices have been optioned by Constantin Film and Unique Features, the same studios making The Mortal Instruments: City of Bones. Not much is known about Infernal Devices other than the project is in development and a script is in the works, but the project is moving forward.

There has been talk about alternating between The Mortal Instruments and The Infernal Devices movies, beginning after City of Glass and starting with Clockwork Angel.

But this all depends on the success of the Mortal Instruments movie franchise.

Are you excited about the possibility of a The Infernal Devices: Clockwork Angel movie?
