As reported by Anime News Network, documentary filmmaker Mami Sunada (Ending Note: Death of a Japanese Salaryman) is nearing completion on the Studio Ghibli documentary Kingdom of Dreams and Madness. The film follows studio producer Toshio Suzuki, and directors Hayao Miyazaki and Isao Takahata (Grave of the Fireflies) as they work on two upcoming Studio Ghibli films, Kaze Tachinu (The Wind Rises) and Kaguya-hime no Monogatori (The Tale of Princess Kaguya).

When discussing her film’s title, Sunada explains: “I think that having a dream entails having a bit of madness, no matter what the profession. There are times when you will go to extremes, and times when you are feared by others for that.”

The Wind Rises, which is the first Miyazaki directed film in five years, debuts this weekend in Japan. Centering on Zero fighter designer Jiro Horikoshi, it is inspired by a manga Miyazaki created for Gekkan Model Graphics magazine and based on the novel of the same name by Tatsuo Hori. The Tale of Princess Kaguya, directed by Takahata is an adaptation of the Japanese folk story, The Tale of the Bamboo Cutter. Originally slated to premiere simultaneously with The Wind Rises, Kaguya’s release date was postponed due to production snags, and as a result, Sunada continues to film in the studio to cover the extended production. Sunada’s documentary will premiere this fall in Japan.
