'Mortal Instruments' Conjures Its Magnus, Jocelyn And Hodge

The streets of author Cassandra Clare's Brooklyn are looking far less deserted thanks to three (!) new additions to the cast of "The Mortal Instruments" movie "City of Bones."

Cassie announced today via her Tumblr that model/actor Godfrey Gao will play magical Magnus Bane, "Game of Thrones" actress Lena Headey will play Jocelyn Fray and "Sherlock Holmes: Game of Shadows" actor Jared Harris will play Hodge.

The author heaped plenty of praise upon the film's fresh faces:

"Godfrey is, in addition to being all gorgeous and stuff, super-talented (his audition was awesome), loves the books, and is, like Magnus, ridiculously tall," she wrote.

"I have had an actress crush on Lena for years so when they told me she was cast I did a happy dance and hit Sarah Rees Brennan on the head with a spoon," she continued. "Actually I would have done that last bit anyway. Lena is amazing and I think she will be amazing as Jocelyn. I am super psyched."

And, as for Jared, "He’s got SAG awards all over the place and I think he’ll really nail Hodge’s moral dilemma."

The trio join a burgeoning cast, which now includes Lily Collins as Clary, Jamie Campbell Bower as Jace, Robert Sheehan as Simon, Jemima West as Isabelle, and Kevin Durand and Robert Maillet as Valentine's henchmen.

The supernatural movie is set to begin filming next month with an August 2013 release date.
