What a cast, but it's not available anywhere that I looked - public and private trackers.

Some random guy on youtube said that it was available on "Japanese Amazon" (Amazon Prime Japan?), at least at the time of that comment. This movie has a Japanese poster too, so I think this info is legit. Blu-ray.com doesn't know about any digital release, but 141 ratings on IMDB is still more than "only the filmmakers saw it".

Is it available anywhere?
