Hayao Miyazaki wrote the script for the film based on Norton’s novel. Directing is 36-year old Hiromasa Yonebayashi, who served as a key animator on Miyazaki’s classics Princess Mononoke, Howl’s Moving Castle and Spirited Away. He’s the youngest feature director in Studio Ghibli history. Miyazaki has long wanted to adapt the novel (The Borrowers), and is overseeing the production.
