Newt Scamander is the Wizarding World’s preeminent "magi- zoologist", who writes the Hogwarts school textbook based on the magical beasts he's encountered and documented in his travels. That's a book that's been on my muggle son's bookshelf next to his HP books since it was first published in 2001.
On the required reading list for all first year Hogwarts students—which apparently can be filled via Amazon—Fantastic Beasts and Where to Find Them is a detailed introduction to the magical beasts of the non-Muggle world, including a few familiar examples like Hippogriff, Flobberworm and Kappa along with some species you've never heard of. "Learn what a Chizpurfle is, or why one should always beware of the sinister Lethifold"

I can so easily picture Redmayne scurrying across the non-muggle world, sketchbook in tow, detailing his findings like a magical version of Charles Darwin! Picture his portrayal of Stephen Hawking(above) before he was stricken by ALS.
Kate Upton (The Other Woman)—it's almost impossible to find an image of this swimsuit and undies model without boobs spilling out of her top, this is one of the few I could find—Katherine Waterston (Inherent Vice) and Elizabeth Debicki (The Great Gatsby) are up for the part of Queenie, Tina’s older sister.
Since I'm not a helicopter parent, I didn't even flip through my son's copy of the Hogwarts textbook (muggles with very high scores on their entrance exams were given a waiver to audit the class) so I'm counting on you to explain their potential roles.
