The films of Koji Fukada have long wrapped ambitious themes in deceptively unassuming genre packages. His 2011 international breakout "Hospitalite" ("Kantai") begins as a quirky comedy but becomes a sharp-edged drama of deceptions and secrets. Last year's "Sayonara" starts as an offbeat essay in apocalyptic sci-fi, centering on a terminally ill woman and her robot caregiver, but transitions into a stark examination of death and dissolution.
