Thanks again to EW, we now have character descriptions of all main Fantastic Beasts characters:
Eddie Redmayne as Newt Scramander
An eccentric globe-hopping English “magizoologist” wizard who’s far more comfortable around beasts and creatures than he is around other people. Comes to New York on a quest with his case full of magical habitats containing rare and endangered species.
Katherine Waterston as Porpentina “Tina” Goldstein
An ambitious worker at the Magical Congress of the United States of America (aka MACUSA, the U.S. version of the Ministry of Magic) who meets Newt. Tina is relegated to an office well below her abilities after she stood up for the wrong person. She longs to fight for what’s right.
Alison Sudol as Queenie Goldstein
Tina’s younger sister and roommate, a big-hearted free-spirit “legilimens” who can read minds.
Dan Fogler as Jacob Kowalski
An optimistic No-Maj (aka Muggle) factory worker/aspiring baker who gets introduced to the wizarding world when he meets Newt. Fun fact: He’s the Harry Potter franchise’s first Muggle main character.
Colin Farrell as Graves
A powerful auror and the right-hand man of the American wizarding world’s president.
Samantha Morton as Mary Lou
The narrow-minded leader of the fanatical Second Salemers, a group looking to expose and destroy wizards and witches.
Ezra Miller as Credence
Perhaps the cast’s most mysterious character. He’s Mary Lou’s troubled adopted son.
