I have gone back to the wonderful STEPHEN KING Book CARRIE; I am also modernizing the story as one has to in order to bring any great piece of work written in one era into the next and especially given how very relevant this material is right now.
Chloe is going deep into character to get this right....sewing her own dresses, spending time in her closet....and so much more....Thanks for all the great wishes. We are on it! And privileged to be working with such great source material.
A more modern anit-bullying message is probably appropriate for an updated Carrie, but tell that kid she really doesn't have to spend time in her closet.
