The news comes during a big week for Harry Potter author JK Rowling, whose script-book for the play "Harry Potter and the Cursed Child" (by Jack Thorne, based on a story by himself, Rowling and director John Tiffany) debuted on Sunday and sold 2 million copies in its first two days.
Rowling and her Pottermore team are betting big on continued interest in the wizarding world, and the "Fantastic Beasts" movie franchise is conceived as a trilogy, reported Variety.
The first movie tells the story of Newt Scamander (played by Eddie Redmayne), author of Harry's future textbook, traveling to New York City in the 1920s with dangerous magical beasts in tow.
Warner Bros said the second movie "moves deeper into an increasingly dark time for the wizarding world, where Newt and our other heroes have to decide on their allegiances.
