I have to be honest and say that I was quite underwhelmed by this. Whilst Jean Renoir has certainly produced a beautifully gritty film that evokes a genuine sense of how life on the French Chemin de fer might have been in the late 1930s', this left me feeling that a great deal had been lost between the book and the screen... "Roubeau" is a forty something railway conductor who has a much, much younger wife. When he discovers that she has had an affair with her godfather, he forces her to arrange a meeting on his (moving) train and kills him. Whilst not actually witnessed by fellow railway worker "Jacques Lantier" (another strong performance from Jean Gabin); he saw them leave the compartment and he covers for them at the subsequent enquiry - he, too has fallen for her! Though there are doubtless some enthralling scenes - particularly as he and his femme fatale; a rather insipid looking Simone Simon find their relationship become truly toxic; the story just doesn't quite catch fire for me. It's a rather melodramatic interpretation of Zola's novel - and though it is broadly faithful to the book; it lacks much of the nuance and by allowing us to see full on; rather than allow our imagination to drive our feelings about the complex relationships and demons that each of the three principal charters face, it delivers us with some stark characterisations that I didn't appreciate so much; I just didn't really empathise with them in anything like the same way as I did when I read the book. Again, Jospeh Kosma delivers a super score to accompany this; and the cinematography - especially in/around the trains is as authentic as I have seen. A good but not great film.
