Fantastic Beasts and Where to Find Them: the Original Screenplay

The variety of creatures felt so vivid and imaginative. I'm curious whether the author based some on real animals or crafted them purely from imagination.

I loved the world-building, but the initial setup felt a bit drawn out. Do you think this was necessary to introduce the magical society properly?

Writing a screenplay brings a different rhythm and focus. I wonder what challenges or advantages the author experienced in translating their story into this format.
