Based on a script by Clouzot, the aim of this movie is to describe the patholgy and psychology of man, Francois, who succumb slowly under the weight of jealousy. This movie is amazing, and describe the psychological aspect of this "disease" in a very defined way. Clouzot has actually done a long study of the phenomenon of jealousy, it is therefore highly detailed and enlighted by Chabrol art to slow down the pace of the movie up to the point that, just like Francois, time seems to be infinite. It's a mental torture for Francois, he is prisoner of his thoughts and his mind killing the reality slowly. This movie is a must see!!!!
