Lily Collins poses with Kevin Zegers, Jamie Campbell Bower, Robert Sheehan and Jemima West in this new cast pic from a recent photo call for The Mortal Instruments: City of Bones in Toronto, Canada.

The five stars of the film met up with press outlets to kick off production for the book-based film, which is set for release in August 2013.

Set in contemporary New York City, a seemingly ordinary teenager, Clary Fray (Lily Collins), discovers she is the descendant of a line of Shadowhunters, a secret cadre of young half-angel warriors locked in an ancient battle to protect our world from demons.

After the disappearance of her mother, Clary must join forces with a group of Shadowhunters, who introduce her to a dangerous alternate New York called Downworld, filled with demons, warlocks, vampires, werewolves and other deadly creatures.
