The Harry Potter author confirmed via twitter that there will be two additional Fantastic Beasts films due for release, making it three in total. So that's Eddie Redmayne sown up for a while.
You heard wrong, I'm afraid. #CursedChild is a play. #FantasticBeasts will be 3 movies, though! https://t.co/7tvw4rolcR

Us Weekly reports: "Fantastic Beasts and Where to Find Them, which will be released on November 18, stars Eddie Redmayne as Newt Scamander. As fans of the series know, the title is also the name of a text book about magical creatures written by Scamander 70 years before the Boy Who Lived gets to Hogwarts."
As for #CursedChild, while it may exist as a play, it is getting a new book. It's due for release in July this year.
