I wrote elsewhere on September 17th of last year:
With regard to Zombie Ass: Toilet of the Dead, the screenplay for it was written by Ao Murata, Jun Tsugita, and Noboru Iguchi. Yasutaka Nagano was the cinematographer for it. Nori Fukuda was the production designer for it.
BTW, Tsugita, Nagano, and Fukuda worked in the same capacities on Takashi Murakami's live-action Jellyfish Eyes (Mememe no kurage), which is now in post-production. That movie is being produced, in part, by Yoshihiro Nishimura and his Nishimura Eizo Co. Ltd. (Y.K. Nishimura Eizô) - a.k.a. Nishimura Motion Picture Model Makers Group (NMPMMG).
Today (August 1st) was the first day of filming (crank in / kuranku in) of Murakami's Jellyfish Eyes 2 (Mememe no kurage 2).
