‘Mortal Instruments’ Star Lily Collins Describes Her Ideal Jace

'He's got to have wit but also be very vulnerable,' she tells MTV News.

Although “The Mortal Instruments” movie has found its Clary Fray, via actress Lily Collins , there are still a few big roles to be cast — mainly one Jace Wayland, Clary’s is-he-or-isn’t-he love interest.

We’ve had some fun speculating about rumored contenders and fan favorites, but when MTV News sat down with Lily Collins at WonderCon recently, we asked her to comment on the heated casting competition — specifically, what they’re looking for in their future Jace. (Head to our Hollywood Crush blog for everything we’ve got on Cassandra Clare’s fourth “Mortal Instruments” book, “City of Fallen Angels,” which hits stores Tuesday.)

“Jace is confident and knows he’s confident,” Collins explained. “He’s good-looking and knows he’s good-looking. He’s got that je ne sais quoi, in that he walks into a room and you go, ‘Wow.’ He knows he’s the best thing in the room. He’s got to have wit but also be very vulnerable, and I think it’s hard. I think a lot of actors don’t necessarily want to show vulnerability, but [for] this character, it’s completely necessary but, at the same time, that overconfidence as well. I think it’s going to be that thing where they walk into a room and you do a reading and go, ‘Wow, I really can’t see anyone else as this character,’ so it’s going to be an interesting process.”

Collins said she has read with several actors, but wouldn’t expand upon any favorites, like Alex Pettyfer, but was tightlipped to expand upon any favorites or which actors the filmmakers have preferred, but she will be involved in casting Jace.

“The amazing thing is that they really want my input, which is a complete honor,” Collins said. “They want me to be involved in the process. Having been the first cast in the series, they want my input on the character, so that’s huge for me.”
