Just as one wildly popular literary adaptation starring Lily Collins is about to hit theaters (that'd be Mirror Mirror, out March 30), the actress has signed up for another: Cassandra Clare's The Mortal Instruments. Harald Zwart (2010's The Karate Kid, et al.) will direct.
Collins will play lead character Clary Fray, a seemingly normal teenager forced to navigate New York City's demon-inhabited underworld -- with the help of Shadowhunters -- after the disappearance of her mother.
Producer Robert Kulzer issued the following statement regarding the suddenly red-hot Collins' casting: "Lily Collins is the perfect Clary. Harald Zwart really understands the visuals and heart of 'The Mortal Instruments.' That was crucial to us. Of course, having Cassandra Clare's support throughout and collaborating with her on this project has been especially rewarding."
