BATTLE ROYAL (damn good action film in general based on a comic)

TABOO (1st japanese, and so far the best, film I've ever seen!)
Director: Nagisa Oshima. It has won multiple awards.

"It shows life in a samurai training school during the bakumatsu period, the end of the samurai era in the mid-19th century, specifically concentrating on the issue of homosexuality in the shudō tradition in the partially-closed environment." -Taboo (1999 film) - Wikipedia, the free encyclopedia

KAGEN NO TSUKI (btw, Hyde in one of the main roles as Adam)
Love story of such an passionate emotion that has the power to defeat even death itself. Besides; it's visually pretty piece of work. Can probably also be found from the net for free watching if someone wishes to do so.
