The casting call was just put up in LA for the Shadowhunters TV show! It sounds like they are going to be starting back at the beginning with COB, despite the movie they already made. The only difference I saw in the character descriptions (they only had Clary, Jace and Simon) was that the characters are going to be a bit older. Clary will be celebrating her 18th birthday, not her 16th, and Jace will be early 20s. A tweet was released on March 4th by a “Lindsay B” (someone working on the show??) saying the TV show will start filming in Vancouver (Canada) in May 2015!
