ET EXCLUSIVE VIDEO: Behind the Music of 'The Mortal Instruments'

An incredible brand new video has been released by ET Online going behind the music of The Mortal Instruments: City of Bones. It can be seen below!

Mirror Mirror star Lily Collins faces a variety of decidedly nasty demons, warlocks, vampires, werewolves and other deadly creatures in the new thriller The Mortal Instruments: City of Bones, now in theaters, and we have an exclusive look behind the scenes at the making of the original motion picture score by Atli Örvarsson.

Örvarsson was hired on the spot by Harald Zwart at the premiere of Hansel & Gretel: Witch Hunters (for which Örvarsson provided the music) to compose the score for City of Bones -- with only three weeks to complete the score for the film after replacing an Oscar-winning composer who left the project.

"I came out of a screening of another film Atli previously scored and there was a certain energy about it," says Zwart. "I thought, 'He's the perfect man for the job.'"

After watching the film's first cut, Örvarsson immediately presented Zwart with a piece of paper containing the main heroine's theme. In a short time, the soundtrack was recorded at Abbey Road Studios in London, incorporating a full orchestra and choir.

"He handed me music scribbles and said, 'This is the theme,' and it is the beautiful Clary's Theme we hear in the film," explains Zwart.

Based on Cassandra Clare's best-selling book series, City of Bones casts Collins as Clary Fray, a seemingly ordinary teenager who discovers that she is part of a line of Shadowhunters, a secret force of young half-angel warriors locked in an ancient battle to protect our world from demons. After the disappearance of her mother (Lena Headey), she must embrace her fate and battle supernatural forces in a dangerous alternate New York City called Downworld.

The Mortal Instruments: City of Bones also stars Jonathan Rhys Meyers, Jared Harris, CCH Pounder, Jamie Campbell Bower, Robert Sheehan, Kevin Zegers, Kevin Durand, Aidan Turner, Jemima West and Godfrey Gao.
