I heard it going to be a live action movie. But it kinda going to be a remake of the show. The first movie is going to book 1 water. But that what I hear, it not fact.
If I was the creator I would make a zuko spin off as he tries too figure out wht happend too his mom as thing become more complicated he meets new friend and I would kill his uncle i think that would make him think too all of those that he has lost
