Hayao Miyazaki will be aiding his son, Goro Miyazaki, on the movie, but he will only be part of the planning and development.
As it turns out, Goro Miyazaki will be doing most of the decisions for the movie.
With Goro Miyazaki at the helm, this movie will serve as Ghibli’s first full 3DCG animated feature film.
In fact, during a press conference during a Ghibli exhibition in Aichi Prefecture, the younger Miyazaki says that he didn’t consult the “old men” at the studio at all when making the movie.
