Although the first film in the planned"Fantastic Beasts and Where to Find Them" trilogy won't arrive in theaters for another four months, director David Yates confirmed J.K. Rowling has already completed the script for the sequel.

"We've done the first one, she's written the second one, she's got ideas for the third one," Yates, who helmed four "Harry Potter" films, told GSNews. "No one quite has ownership of them yet, in terms of having a relationship with the material, other than the relationship they'll have with the movie when it comes out, so it's lovely in a way."

That stands in contrast to the "Harry Potter" adaptations, which left out elements of the novels "because they didn't quite work within the structure of the storytelling for the movie, or because the movie would just be far too long." "With this," Yates said, "it's just pure Jo, from the first page to the last page."

Set in 1920s New York, "Fantastic Beasts and Where to Find Them" is an expansion of the "Harry Potter" universe that centers on magizoologist Newt Scamander (Eddie Redmayne), whose textbook is later used by Harry, Ron, Hermione and the other students at Hogwarts.

"Fantastic Beasts and Where to Find Them" opens Nov. 16.
