Étoile aux dents ou Poulou le magnifique (1971)

In the 70s, in the Goutte d'or district, three friends of Algerian origin: Poulou, a failed boxer, Amar, the clumsiest of thieves, and Jibé, a public writer for illiterate compatriots whose lives he knows in detail. As he betrays none of their secrets, he enjoys great prestige in the bistros where he works. The three of them lead a casual life, raising money by illicit means. It's only when Poulou and Amar leave that Jibé understands his isolation and marginalization. The images as well as the sounds help to reinforce the feeling that Paris is a city where he is both at home and a terrible stranger.
