The director of "It" should be Steven king for the simple fact he is the master of pages written. If you can not get Mr. King himself at least try to get him involved. This way the movie will not stray too far from the actual story. If all else fails try to get Wes Craven or even Spielburg they have always produced awesome horror and suspense movies. This is my honest opinion on who should be the director of this the "It" remake. If you can swing this I will definitely make it a point to watch this movie.
