This is the best of Melville's thrillers with magnificent Alain Delon as the expressionless murderous . Delon has striven in vain to repeat this success in numerous subsequent movies at the same genre , similar others known actors as Lino Ventura , Jean Paul Belmondo and generally directed by Henri Verneuil , Jose Giovanni and Jacques Deray . The movie packs a splendid cinematography by Henri Decae , the photography glitters as metallic and cold as a gun barrel . The picture was perfectly directed by Jean Pierre Melville , giving a memorable work . Later his beginning as a post-war forerunner of the 'Nouvelle vague' , he left his style in several different ways as a purveyor of a certain kind of noir movie , creating his own company and a tiny studio . Although retaining its essential French touch and developing a style closer to the world of the American film Noir of the 1940s than any of their other such foray s. Dealing with character-studio about roles damned to inevitable tragedies , powerful finale , stylized set pieces heightens the suspense and tension have place all around the Melville's filmmaking . His movies and singular talent are very copied and much-admired by contemporary directors, specially the 'Polar' or noir French cinema , such as : 'Second breath' , 'The red circle', 'Dirty money' and , of course , 'Le samurai'.
