La Notte by Michelangelo Antonioni (Italy, 1961, 122 min.).
Marcello Mastroianni, Monica Vitti, and Jeanne Moreau star in this enigmatic film about modern alienation and ennui. Mastroianni plays a married novelist who is tempted by another woman (Vitti); Moreau is his disenchanted wife who begins to question her marriage as well as the vapid high-society crowd she runs with in Milan. La Notte was the second film in Antonioni’s existential trilogy, produced between L’Avventura (1960) and L’Eclisse (1962).
