The actor who has had roles in Twilight and Harry Potter will now be having likely his biggest role yet in The Mortal Instruments, it was announced today.

From Variety:

Screen Gems has tapped him to star opposite Lily Collins in its adaptation of “The Mortal Instruments.”

Cassandra Clare’s bestselling young adult book series follows Clary Fray, a seemingly ordinary teenager who discovers she is the descendent of a demon-hunting clan called Shadowhunters. Bower will play Jace Wayland, a Shadowhunter with tattooed arms who is seeking to avenge his father’s death.

Scott Stewart is directing the Jess Postigo-scripted pic, which is expected to launch a feature franchise, as there are six novels in Clare’s series.

We know many of you are big fans of Mortal Instruments, so what do you think of Campbell-Bower getting this big role?!
