Takashi Miike's 46-OKUNEN NO KOI, starring Ryûhei Matsuda, Masanobu Andô, Renji Ishibashi, Ken'ich
Thanks to the official website for Ken'ichi Endô (see below) for bringing the following to my attention: Takashi Miike's 46-okunen no koi is scheduled to be released theatrically in Japan in the spring of next year.
The screenplay for 46-okunen no koi was written by Masa Nakamura, based on the novel Shônen A erejî by "Ato Masaki" - a joint pen-name of Ikki Kajiwara (1936-1987) and his younger brother Hisao Maki. The movie stars Ryûhei Matsuda, Masanobu Andô, Renji Ishibashi, Ken'ichi Endô, Shunsuke Kubozuka (Kuboduka Shunsuke), Kiyohiko Shibukawa (a.k.a. Kee), and Ryô Ishibashi.
