It's true, when I read "Studio Ghibli", I tend to think "Hayao Miyazaki". But Studio Ghibli was founded by Miyazaki, producer Toshio Suzuki, and Isao Takahata. Over the years, Takahata was involved in some of the studio's greatest films: Grave of the Fireflies, Nausicaä of the Valley of the Wind, Kiki's Delivery Service, Only Yesterday, and others. One thing that separates Takahata from people like Miyazaki is that he performs many different roles in the movies ... he was even the musical director for Kiki. The Tale of the Princess Kaguya was his final film before his death. The problem for me is that I don't know enough about the process of creating animated movies, so it's not clear to me what role Takahata plays in Kaguya. He is the director and co-writer, but to the best of my knowledge, he doesn't do the animation. I'd be happy to be better informed about this, but Takahata appears to be a titan of animated films without being himself an animator.
Which doesn't really matter ... The Tale of the Princess Kaguya is a beautiful film, no matter who we credit. Takahata seems to be the guiding vision behind the film. It has the look of animated watercolors ... it doesn't really look like any other film that comes to mind. The story is based on an old Japanese story about a bamboo cutter. It is filled with fantastical elements, yet the story is straightforward. It is currently #350 on the They Shoot Pictures, Don't They list of the top 1000 films of the 21st century (which had its most recent update on February 1). Nominated for an Oscar as Best Animated Feature (the winner was Big Hero 6).
I watched the English dub, with Chloë Grace Moretz as the Princess. She is fine. I don't want to be a broken record, but this movie really is beautiful, and wonderful to watch.
