J.K. Rowling is continuing her relationship with BBC One as the Harry Potter author works on multiple film and TV follow-ups to her hit book-turned-movie series about the boy wizard. Rowling’s Cormoran Strike crime novels, written under the pseudonym Robert Galbraith–beginning with the best-seller The Cuckoo’s Calling–will be adapted for a major new drama series for BBC One, produced by the author’s Bronte Film and TV production company.
