The short film was created for a gallery exhibition, and was directed by Hideaki Anno (Neon Genesis Evangelion), and is based off characters from the Studio Ghibli film Nausicaa Of The Valley Of The Wind.
The big question now, is that was Studio Ghibli testing the waters for live action, or was this more of a one-off deal? There’s no word as of yet if they are planning to adapt this into a feature-length film, but if the response is good enough, I wouldn’t be surprised to see this on the horizon.
