Fantastic Beasts and Where to Find Them: The Original Screenplay by J.K. Rowling is exactly that, a screenplay of the movie Fantastic Beasts and Where to Find Them (2016). 
 This movie/screenplay storyline is inspired by the textbook of the same name that was released in 2001 also by J.K. Rowling (Part of the Hogwarts Library Series). Fantastic Beasts and Where to Find Them is a bestiary of magical creatures from the Harry Potter universe and proceeds from the sale of the original textbook version go to Comic Relief. 
 With all that out of the way - this screenplay was a fantastic (see what I did there?) read. Having seen the movie first it was like watching it all over again but in my mind. The scene descriptions, the dialogue, everything was just like the movie. It was a quick and enjoyable read and if there are future screenplay versions of the next four Fantastic Beast movies made available I will definitely be interested in reading them also.
