Instead of an adaptation, this will be another original work for the animated filmmaker. The story delves into the lives of a 5-year-old boy named Sosuke, the image of whom will be visually modeled after Miyazaki's grandson, and a princess goldfish named Ponyo who is aching to become human. As for more details, Ghibli World says that the film will deal with themes of "father," "mother" and "cliff," which I'm sure is all the specifics you were looking for, right? "Cliff" makes things ominous, but the president of Studio Ghibli, Toshio Suzuki, has said that "Almost 70 to 80% of the film takes stage on sea. It will be a director's challenge on how they will express the sea and its waves with freehand drawing." Hmm. Waters and cliffs and I'm sufficiently confused. How about you?
