These are some of my favourites, some may be already listed, I read the thread, but I have a bad memory---
Three Extemes
(three movies from three different Asian directors, one of whom is Takashi Miike) all shorts, all horror genre, all good. Korean/Chinese/Japanese
Bright Future
Movie by Kiyoshi Kurosawa about a violent boy who breeds a killer species of freshwater jellyfish, well, that's part of it---
Electric Dragon, 80.000v
Kind of a long music video almost by Koroshiya 1 (Ichi the Killer) star, Tadanobu Asano... black & white---
Happiness of the Katakuris
Another weird Miike film, I don't really know how to describe this except for it's almost a musical, but very very strange (Miike after all----)
Wild Zero
This film is about space zombies and the j-rock band Guitar Wolf, who apparently are more famous OUTSIDE of Japan than in it, from what I can tell--- it's great, especially if you like zombies and 50s greasers...
Stacy
This is another fun movie w/ zombies (aka Stacy's), except that the zombies are girls who before becoming completely zombie-fied fall into a trance like state where they act extremely bubbly and happy---
Survive Style 5 Plus
This movie is pretty great, but I haven't finished watching it (I watch fewer Japanese movies living in Japan... I don't know why---)... it has Tadanobu Asano, the townie guy from Shimotsuma Monogatari (who also is on a tv-dorama as well...), and Vinnie Jones of Snatch/Lock Stock & Two Smoking Barrells fame...
Cutey Honey
This movie should really anoy me, but it doesn't---- it's basically live action anime almost w/ model Eriko Sato as Honey--- It's pretty stylized and at times cheesy, but so is the original anime so, it's not like they are plodding on the retelling of Les Mis'....
Zatoichi
A lot of people cry foul about Beat Takashi's version of Zatoichi, the other guy who stared in like 50 of them, died apparently--- I haven't seen the previous versions so I can't say, but on it's own, it's a great ronin meets masseus meets musical sort of thing--- lots of swords and music based around an older era of Japan...
Also, it was mentioned but, it's worth mentioning two films,
Casshern, a sort of sci-fi action movie that doesn't have a lot of 'sci fi', but a lot of 'sci' i guess--- no spaceships just future--- and
Nobody Knows, aka
Dare mo shiranai, based around the true story of a group of kids who were left to live alone in a house by their wayward mother (played by 'You'--- the hardest name in the world to google---)... All of the characters had no script and basically improvised each shot.
Also, this is a great site that has movie news and reviews on Japanese films
Midnight Eye - Visions of Japanese cinema - interviews, features, film reviews, book reviews, calendar of events, links and more...
