INFO: According to Cassandra Clare’s livejournal, The Mortal Instrument Series has been optioned by the film production company Unique Features.
Cassandra states in the post:
Now, a book series being optioned doesn’t mean a film is being made right now or is definitely going to be made at all — it means that the studio or production company in question is developing the books as a film project — right now they’ve nailed down financing and a screenwriter (I don’t know who that is yet) and are working towards the next stages in the development project. It is, however, an important step in the movie-making process, so I feel like it’s okay to be excited about it.
