Kind of semi-vague this. Big fan of Kiyoshi Kurosawa personally. Lovely films.
Anyhow, I know IMDB lists "Ghost Cop" as his latest entry after "Doppelganger" (which i personally loved), but according to jasongray.net there's also "Shi no Otome" or "Maiden of Death) to come. The site, which i found yesterday, shows in a september post and a couple of small pics. Jason says he has a copy of the screenplay but hasn't read it (he's also in the film!) - it's also apparent Jason has connections with Artsmagic and seems to be conducting interviews for other DVD releases.
"Ghost Cop" i believe to have been shown at a recent "Cop Film Festival" in Japan, but i cant find any more info. "Shi No Otome" (as far as i know) han't been mentioned anywhere other than Jasons' site. Anyone got any more on either of these?
