There's a trailer for Takashi Miike's Waru (working title was "Waru: Final") on the page for the movie on the website of goo (NTT Resonant K.K. / K.K. Enu Ti Ti Rezonanto).
The screenplay for Waru was written by Hisao Maki, based on the 3-volume gekiga Waru: saishû-shô (vol. 1, vol. 2, vol. 3) by Maki (story) and Jôya Kagemaru (drawings). The movie's principal cast is as follows (listed order corresponds to trailer order): Shô Aikawa, Maki, Nagare Hagiwara, Keiko Matsuzaka, Ryô Ishibashi, Shion Machida, Tamio Kawachi, Hideki Sone, Atsuko Sakuraba, Satoru Sayama (a.k.a. Tiger Mask), Akira Maeda, Hitoshi Ozawa, Johnny Ôkura (Jonî Ôkura), and Masumi Okada. The rest of its cast apparently includes Yoshihiko Hakamada, Kimika Yoshino, Kôki Okada, Hikaru Kawamura, Saki Kurihara, and Guts Ishimatsu (Gattsu Ishimatsu).
Maki Production (Maki Purodakushon) is scheduled to release Waru theatrically in Japan on February 25th.
Miike's other recent/upcoming movies include Big Bang Love, Juvenile A (46-okunen no koi) and Masters of Horror: Imprint. The former is based on the novel Shônen A erejî by "Ato Masaki" - a joint pen-name of Maki and his elder brother Ikki Kajiwara (1936-1987).
