There appears to be no shortage of brawling youth pics out of Japan. Add to the growing list Furyou Shounen: 3000-nin no Atama which the automatic translator turns into The total number to 3,000 people a bad boy (sometimes there). I'm just going to take their word for it on that one.
The book was written by Endo Natsuki, who was once affiliated with the biker team and band COOLS. 30 year old actor Saito Takumi [Takashi Miike's Phoenix Wright and Space Battlehsip Yamato] will play the lead Sendo who must battle his way to the top of his school.
The supporting cast includes Kubozuka Shunsuke, Iwanaga Hiroaki [Tomica Hero and Kamen Rider OOO Wonderful], Sudo Atsuko, and Hotta Shinzo. The film is directed by Miyano Keiji and will be released in Japan next March.
