Poetic Realism is the first, great French cinematographic tendency of sound movies, developed between 1930 and 1940.
The film belonging to this genre are tipically set in cities, in the slums, where the least-favoured social classes hang out. The main characters come from here, almost always damned characters, on the borders of society, whose story is inevitably determined by their own fatalism.
Another distinctive feature: dialogue. The word is the center around which the scene develops, and the main way to narrate the key moments of the plot.
One of this genre’s masterpieces is the 1945 movie, Les Enfants du paradis, directed by Marcel Carné and written by Jacques Prévert.
