After the huge success of the Harry Potter movies, the overwhelming money-making power of the Twilight franchise, and the gargantuan debut of the first Hunger Games film, it was starting to look like adaptations of Young Adult literature were going to be the new go-to when it came to tentpole filmmaking—the new super hero movie, essentially. The longevity of the YA trend got called into question, however, when The Mortal Instruments: City of Bones, which was the first film adaptation of a series of wildly popular YA novels by author Cassandra Clare, came and went at the box office without making so much as a peep. Suddenly studio execs had to start asking themselves a bunch of questions about the future of supernatural love triangles. Was it possible that the YA craze had come and went already? Was there something about this particular property that didn’t translate as well to the screen as the successes that came before it? Eventually concerns around City of Bones’ sluggish box office returns became so great that production on the sequel, City of Ashes, was halted indefinitely just a week before it was scheduled to begin. That didn’t seem like a good sign for fans who were hoping they’d get movie versions of all three installments of Clare’s initial “Mortal Instruments” trilogy.
