Story here. “Rowling’s first-ever screenplay is expected to be the first of a series of new films about the wizarding world that fans know well from the Potter books and movies.”
Set in the same universe as Harry Potter, but 70 years before, and according to Rowling “not a prequel”. Main character is Newt Scamander, author of one of the textbooks in the Potter series. Rowling will write the script - no word if there will be a novel as well.
According to canon, it’s set too early for Voldemort to appear (movie set in 1918, V born 1926), but just perfect for a younger Dumbledore (born 1881) to show up. Given that Rowling recently said he’s the character she misses the most, I wouldn’t be surprised a bit if he finds his way into the movie.
So what do you think? Rowling can’t resist going back to where she started? Admitting her other novels will never go anywhere? Naked cash grab?
