"Mortal Instruments" fans might get crazy as there is a rumor that "Mortal Instruments" TV series will include original casts such as Lily Collins and Jamie Campbell Bower.

It seems that Clarissa Hamlin, the movie section editor of Fashion Style is also a fan of this movie. Based on her article, Cassandra Clare, writer of "Mortal Instruments" and "Infernal Device," said she doesn't know about the development of the film, but she only knows that TV series will surely begin with "City Of Bones."

So the next question arising from the fans is if the original film casts will reprise their roles or if there will be a new batch of cast?

Some might want to bring back Colllins and Bower. FS style author said that Change.org , a website made for petition, reportedly receives more than 3,000 supporters who are in favor of bringing back the original cast and reprise their roles.

Bower reportedly tweeted that he had some "new and exciting" projects coming up for 2015. This made fans get intrigued if this is about "The Mortal Instruments" series.

However, there is a rumor floating around that Brenthon Thwaites of "The Giver" will take over the Jace role.

"Mortal Instruments" tv series casts are still a mystery as the names currently appearing for the roles are considered rumor. Will the petition from Change.org affect the casting of this upcoming TV series? To know more about the development about this TV series, keep tabs on Kdrama!
