After a slew of casting announcements, principal photography has begun in England on the Harry Potter spinoff, Fantastic Beasts and Where to Find Them. The film stars Eddie Redmayne as Newt Scamander, “the wizarding world’s preeminent magizoologist, who stops in New York following his travels to find and document magical creatures.” The story takes place seventy years before the events of the Harry Potter films.

Warner Bros.’ press release also reveals that the talented Samantha Morton (Minority Report) has joined the cast, and will play Mary Lou. The film also stars Katherine Waterston as Tina, Alison Sudol (Dig) as Tina’s sister Queenie, Dan Fogler (Fanboys) as Jacob, Ezra Miller (Trainwreck) as Credence, Jenn Murray (Brooklyn) as Chastity, Faith Wood-Blagrove as Modesty, and Colin Farrell as Graves.

We don’t know much about these characters other than Jacob is a muggle, Credence is a rival of sorts to Newt, and Graves is a wizard that Newt meets while in New York. I’m absolutely fine with as much of this movie remaining a mystery for as long as possible.

Check out the full press release below. Directed by David Yates and written by J.K. Rowling, Fantastic Beasts and Where to Find Them opens in 3D and IMAX on November 18, 2016.
