This is the second of six films directed by Marcel Carné between 1938-46 which are the foundation of French poetic realism. Though without his usual screenwriter Jacques Prévert, there is more realism, and less poetry. It's an ensemble melodrama set among the residents of the title address.
What makes this most like other Carné films is the romantic pessimism of the central story about a juvenile couple who can't make a living in the depression, so check in to execute a double suicide. Annabella and Jean-Pierre Aumont are extremely beautiful and affecting in the roles.
There's a wonderful support cast of French character actors, but the emphasis of their stories is unbalanced by the charisma of Arletty and Louis Jouvet as a sex worker and her pimp. Watching them bicker while shacked up in bed spotlights how much more adult late '30s French cinema was than Hollywood.
There is an awful lot of infidelity going on! The huge set of the Canal St. Martin and Maurice Jaubert's romantic score bring atmosphere. It's arguably the least of Carné's releases around the war years, but the image of the young lovers wresting with malign fate in the dark of their temporary room is among his most potent.
