Who remembers Mohamed Zinet? In the eyes of French spectators who reserve his face and his frail silhouette, he is simply the “Arab actor” of French films of the 1970s, from Yves Boisset to Claude Lelouch. In Algeria, he's a completely different character... A child of the Casbah, he is the brilliant author of a film shot in the streets of Algiers in 1970, Tahya Ya Didou. Through this unique work, Zinet invents a new cinema, tells another story, shows the Algerians like never before. In the footsteps of his elder, in the alleys of the Casbah or on the port of Algiers, Mohammed Latrèche will retrace the story of Tahya Ya Didou and its director.
