The Pornographers (1966)

Mr. Ogata lives a complicated life: he is a pornographer making two skin flicks per day and trying to stay beneath the radar screen of the local mob; he deeply loves his ailing wife Haru who's cursed by the restless spirit of her dead first husband; he also has a mistress, a step-son who wants to go to university, and a step-daughter entering adolescence. He lusts after his step-daughter, and when Haru finds out about those sexual advances, she asks him to marry the girl. Haru even signs over her business to him, and a crisis ensues when Ogata uses her nest egg to buy equipment so he and his pals can set up their own film processing lab. Surreal images and events weave their way into Ogata's life.
