So let the theorizing begin! (Not yet, since we know so little, but let's get this hype train a-rolling!)

In terms of characters, aside from the already familiar cast of Newt, Tina, Queenie, Jacob, Credence, and Grindelwald, we're getting:


Jude Law as young Albus Dumbledore


Zoe Kravitz as Leta Lestrange


Callum Turner as Newt's brother, Theseus Scamander


Claudia Kim as "The main attraction of a Wizarding Circus and Freakshow."


Ingvar Sigurdsson as Grimmson the Bounty Hunter


William Nadylam as Yusuf Kama


Ólafur Darri Ólafsson as Skender, Head of a Wizarding Circus and Freakshow.
