Le Samouraï 1967 The perfectionist serial killer who never loses his composure has finally emerged. Hit man Jeff Costello, always meticulously prepared for his murders, is spotted by someone who killed the nightclub owner. He tries to prove that he was elsewhere at the time of the murder, but is cornered. This experiment, which we will call film noir, remained calm throughout the film, stood out with its style and deeply influenced the art of cinema. There are even references to the Samurai in many movies.
