The first trailer for the film-adaptation of The Mortal Instruments: City Of Bones has just been released and it looks like it could be somewhat of a fix for tweens now that the Twilight series has wrapped up. The film is based on a young adult urban fantasy series set in New York and written by Cassandra Clare, with this film being the first in the series.

The story follows a teenage girl named Clary Fray (played by Lily Collins) who witnesses a murder and subsequently finds herself in a hidden world of demons and Shadowhunters. The Shadowhunters are a group of half-human, half-angels, who fight demons in order to protect the world. The film also stars Jamie Campbell Bower, Jonathan Rhys Meyers, Kevin Zegers and more. An interesting fact is that Alex Pettyfer was offered Bower’s role originally, but ended up turning it down.

The Mortal Instruments: City of Bones comes out on August 23, 2013. In the meantime, check out the first trailer below.
