The movie was never finished in 1964, so this is 'only' a documentary. The movie could have been a breakthrough, but director Henri-Georges Clouzot, who got unlimited budget, kept making experiments. The lead actor, Serge Reggiani, finally walked away. Shortly after, Clouzot himself got a heart attack in the shooting location, while filming a scene of his two lead actresses, Romy Schneider and Dany Carrel, embracing each other. The project was never continued.
The story focuses on a husband's jealousy over his beautiful wife. It seemed Clouzot wanted to use distorted images, bizzare colour, and disturbing soundtrack. The movie is shot in black and white for normal scenes; and colour is used to portray the husband's wild imagination of his wife's betrayal. It's quite interesting, really. The couple lives near a railway and the train comes at a certain hour. The sound of the train triggers the husband to play with his jealous mind.
The documentary presents costume tests, interviews with the director, a selection of Clouzot's experiments, and scenes shot with the cast. The scenes with the cast are without sound/dialogues, but thankfully Jacques Gamblin and Bérénice Bejo read the most important dialogues for us.
