The award for "Best Direction" at the 1978 Cannes Film Festival actually caps the achievement of a decade for Japan's Nagisa Oshima. His latest film, "Ai no Borei (Empire of Passion)," a ghostly story of doomed love, saw its world premiere as Japan's official entry in the most important international film festival, where over 500 films are seen by thousands of critics and industry representatives in an unbelievably hectic two weeks.
