Screenplay - Fantastic! The movie- fabulous! However, when do we get a new novel? I happen to love the magic of your words. Pls?
J.K. Rowling: I'm working on it (literally). And thank you!
CONFIRMED, GUYS! THERE WILL BE A NEWT SCAMANDER NOVELS!
J.K. Rowling: No, no, no. There won't be Newt Scamander novels. Only movies. Calm down, there!
What we got instead is the screenplay, published in book form, ala Cursed Child. Only this time it's actually being written by Rowling, (although substantially edited afterwards.)
