Of course, J.K. Rowling is also revealing more about the Harry Potter universe through the Fantastic Beasts movies, which are all prequels to Harry Potter.
That’s long before Harry Potter was born, but there are plenty of new details to be learned in the films.
J.K. Rowling is the screenwriter for all of the movies.
The third movie’s production was just delayed, but there are still meant to be five films in that franchise, leading up to the big duel between Albus Dumbledore and Gellert Grindelwald.
