The Inheritance (1962)

On his deathbed, a wealthy businessman announces that his fortune is to be split equally among his three illegitimate children, whose whereabouts are unknown to his family and colleagues. A bevy of lawyers and associates then begin machinations to procure the money for themselves, enlisting the aid of impostors and blackmail. Yet all are outwitted by the cunning of the man's secretary (Keiko Kishi), in this entertaining condemnation of unchecked greed.
