Expanding their longterm, lucrative partnership on the Harry Potterfranchise, Warner Bross and author J.K. Rowling are putting a new film series in the works. Rowling will make her screenwriting debut on Fantastic Beasts And Where To Find Them,an original story based on the Hogwarts textbook that appears on a reading list in the first Potter tome, Harry Potter And The Philosopher’s Stone. This is the first in a planned series of films and will feature magical creatures and characters from the Potter mythology, including the textbook’s fictitious author, Newt Scamander. Rowling says it’s not a sequel or a prequel to the Potter adventures, but will kick off in New York, 70 years before Harry’s story starts. No timeline or director has been identified yet. If the films follow the Harry Potterprocess, they’ll make use of Warner Bros’ Leavesden studios outside London which Warner acquired and revamped after the last Potter film was shot. Warner Bros noted today that the relationship between Rowling and the studio will be managed in London by Neil Blair of Rowling’s literary agency The Blair Partnership, and by Warner UK, Ireland and Spain chief Josh Berger.
