Following the death of Juliette Gréco, I watched the 1951 French film Sous le ciel de Paris by Julien Duvivier.
It’s undervalued film. It begins with an exhilarating fly-over of Paris by night, topped with a voice-over mentioning all these souls in the city for which fate has a thing or two in store.
The ensuing action takes place over a period of 24 hours while many of the participants lives intermingle, making it an early example of hyperlink cinema.
