The second movie adaptation to the shadowhunter books by Cassandra Clare is said to begin filming this year. Lily Collins didn't confirm when filming on "The Mortal Instruments: City of Ashes" would begin, but she did say that there are talks about Collins and Campbell Bower reprising their roles.

Collins plays the heroine Clary Fray, who has a brother Jonathan Morgenstern. Who will play the role of the evil but good looking brother? There have been various suggestions as to who would be suitable for the role. Chace Crawford, "Gossip Girl" alum, was one of several actors suggested for the role, though it is possible they would rather go for someone with the "English" accent.

Ezra Miller from "The Perks of Being a Wall Flower" was also pitched in to play the role of Jonathan Morgenstern. Miller, being a versatile actor, would be perfect for the role alongside Jamie Campbell Bower and Lily Collins. Miller could pull a fantastic evil brother to Clary Fray, but there are some fans who suggest to cast Justin Bieber and Collins' rumored boyfriend, Zac Efron.

Bieber may be a teen pop star but he will not fit the role of Jonathan Morgenstern. He would have to be able to talk in a British accent and of course be able to act-not just try and take his shirt off for teen girls to swoon over his chiseled abs.

Zac Efron, who is a good actor, would do if only he too spoke with a British accent. Efron and Collins have been rumored to be dating and Collins' love interest in the movie "The Mortal Instruments: City of Bones" was Jamie Campbell Bower, the two had an on screen and off screen romance, which would make it awkward for Efron to be on set with the two.

What do you think? Who would be the best suitable actor to play the role of Jonathan Morgenstern?
