The sequel to The Mortal Instruments: City of Bones was set to start filming in the next few months, but now Constantin Films has put the brakes on the project.  The studio announced today (via The Wrap) that production on The Mortal Instruments: City of Ashes has been "delayed," but The Wrap notes that the future of the project is in question.  This isn’t exactly a major surprise, as City of Bones debuted to only $9.3 million in its opening weekend and its worldwide total currently stands at $37 million against a budget of $60 million.

Harald Zwart was onboard to return as director for the YA sequel City of Ashes as was the entire cast, but frankly I would have been surprised if Constantin Films moved forward with the follow-up in the wake of the first film’s box office disappointment.  Though City of Ashes has yet to be officially canceled, I wouldn’t exactly hold my breath for it to get back on track anytime soon.
