Wow... this movie looks beautiful. I have no idea if it's coming to the States or not. I would guess yes since it's getting a ton of press over here, but who knows. Here's a blurb about the film and you'll get the gist of the trailer from reading that:
The story is set in the human realm (Tokyo's Shibuya ward) and the bakemono realm ("Shibutenmachi"). In these two worlds which must not intersect, there lives a lonely boy and a lonely bakemono. One day, the boy gets lost in the bakemono world, becomes the disciple of the bakemono Kumatetsu, and is renamed Kyūta.
