Finally, a pleasant surprise! From several points of view. First, an original script signed Roberto Infascelli, Renato Izzo, Aldo Lado, Ettore Sanzo. Then, well directed and starred. All the actors are natural, especially the great Enrico Maria Salerno. Then Macha Méril, perfect in a role of perverse, depraved, nymphomaniac, bigoted woman. Very good Irene Miracle and Laura D'Angelo, as two beautiful young women who will die on the train. Last but not least, Flavio Bucci and Gianfranco De Grassi, very good as the two villains criminals. Franco Fabrizi, another great Italian actor, is OK in a minor role of a voyeur. In an even more minor role of a nurse, Dalila Di Lazzaro, who had to do some special roles in other Italian future films. The music of the giant Ennio Morricone is unfortunately almost nonexistent. Instead, the cinematography signed by Gábor Pogány is absolutely excellent. Congratulations to Aldo Lado, the director, who has indeed as a trademark: Dry, unemotional tones. There is also a nice song by Demis Roussos at the beginning and at the end of the movie.
