EX. If you didn't already know, J.K. Rowling admitted that she is working on a new film set in the Harry Potter Universe. The Harry Potter film franchise was an unstoppable juggernaut and it does make sense that Warner Bros. would want more material to merchandise. Furthermore, I can't blame Rowling for wanting to return to the world she created. It is a fantastic world that has inspired millions. Perhaps no fantasy franchise has taken such a hold of a popular culture since George Lucas's Star Wars (yes, technically it is fantasy). Yet, rather than getting a sequel, prequel, or a retread of similar tropes, this won't be the most obvious sort of follow-up to the chronicles of the Boy Who Lived.
The new film is based on J.K. Rowling's rather slim children's book for charity, Fantastic Beasts & Where to the Find Them, based on the textbook of the same name from the original Harry Potter series. There is some potential in a book that follows some fantastic adventure, presumably Newt Scamander, as he documents creatures in the wild. Or perhaps it is something completely different and completely awesome. We'll just have to see what Rowling's magic can produce.
