The saga of Harry Potter is known all over the world but was it written by J.K. Rowling?The theory was disseminated by the Norwegian director Nina Grunfeld. According to her, the story of a poor housewife who becomes rich writing fantasy books is too good to be true. Her suspicion is that a group of writers created these stories, putting an actress to play the role of author so that the audience feels identified with their life’s efforts and achievements. It is rare that the theory comes from a person like Nina Grunfeld, but her argument is that Harry Potter has too much marketing and is very well thought out.
