Ruiz mastered the absurdist black comedy with Ce jour-là, a whiplash-inducing parody of the ensemble whodunit. The story follows a madwoman, Livia (Elsa Zylberstein), living in near-future Switzerland who’s the sole heir to her departed mother’s fortune. In deep hock after a bad business deal, her remarried father (Michel Piccoli) hires Pointpoirot (Bernard Giraudeau), a psychopath from the nearby sanitarium, to bump her off. A pileup of cadavers ensues, and Ruiz’s screenplay reveals itself to have big things on its mind: life and death, heaven and earth, capitalism and totalitarianism—all tied together by Zylberstein’s singular performance, toggling between dumbfounded naif and mischievous conspirator.
