This is a pretty hyped up about movie this summer. Came out in Japanese theaters August 22 2009, premiered internationally July 28 2009 in Montreal, American premiere will be September 25 2009 at the New York Anime Festival. (North American premieres are JPN audio with ENG subtitles).

Looks to me like rather high-brow anime film. DVD comes out October 28, 2009 so I guess I wait until them for subs.
