The 48-year-old author and Warner Bros agreed to the big-screen adaptation of her 2001 fictitious textbook used by students at Harry Potter’s Hogwarts School Of Witchcraft and Wizardry.
The series was first announced in September as a project, but Warner Bros CEO Kevin Tsujihara told the New York Times on Saturday that the films would be a trilogy.
Rowling will write the screenplays, which will be set in New York and follow “magizoologist” Newt Scamander.
There are no details regarding castings or a release date.
