Whether The Mortal Instruments will become a TV series is still in that rumor stage where it might happen, but might not happen, but probably will, eventually. It’s that on-the-fence stage that leaves fans wanting to know more, even if the answer is that it won’t happen. Nonetheless, in my research (haha, this is just a fancy way of saying I Googled), I learned that if the show were to happen, the story would restart from the beginning thus ignoring everything good and bad about the movie. This would also allow the production company to cast actors who have the time to make a series and may not cost as much as other actors. Still nothing’s definitive so we’ll have to play the wait-and-see game.
