Akihiro Kitamura

The latest from Japan's enfant terrible Sion Sono (Why Don’t You Play in Hell?), a rap musical set in near-future Tokyo where 23 rival tribes struggle for control against a backdrop of Tarantino-esque violence, sex and corruption.

Severed-tongue-in-cheek flick from cult Japanese writer-director Sion Sono (Cold Fish, Suicide Club) about a group of wannabe documentary movie-makers who inject their flash-mob filming technique straight into a yakuza-filled gangwar.

The most disgusting film at this year’s Festival is also possibly one of the funniest, with a sick conceit that will have you either clambering for a ticket or running a zillion miles in the opposite direction...
