Poster - Karigurashi no Arrietty (The Borrower Arrietty)
Studio Ghibli's first movie poster for their upcoming adaptation of The Borrowers, Karigurashi no Arrietty, has been available for a few weeks, and I've found it growing on me. Call it a hunch, a gut check. I really don't know any more than you do at this point. I'm just thinking of the previous Ghibli films not directed by Hayao Miyazaki or Isao Takahata: I Can Hear the Sea, Whisper of the Heart, The Cat Returns the Favor, Tales From Earthsea.
Of those films, Mimi/Whisper is easily the best. And that's largely because director Yoshifumi Kondo's long working relationship with Miyazaki and Takahata. Kondo had many years to learn and study and collaborate; he also had time to develop his own style as an animator and artist.
Arrietty's director, Hiromasa Yonebayashi, has worked with Miyazaki on The Imaginary Flying Machines, Mei and the Kitten Bus, and has worked at Ghibli since Mononoke. GhibliWiki has an excellent piece on Yonebayashi-san from a 2000 NHK documentary on Spirited Away, Breathing Life Into Drawings. You can read about it here.
