Six people share a sleeping-car on a Paris-bound train. When it reaches its destination, one of them is found murdered. As the police (headed by Yves Montand) frantically search for the the killer, the razor-sharp plot quickens and thickens--as the murderer (always one step ahead of the cops) proceeds to kill, one-by-one, the remaining occupants of the car. Finally only two young lovers are left (Jacques Perrin and Catherine Allegret),and they decide to solve the murders themselves. Wrong move, as the killer(s) zero in on their last remaining quarry. Costa-Gavras first film is undoubtedly his best. He keeps the pace so chillingly frantic that moviegoers (when I first saw the film in its 1965 theatrical release) literally gasped at each twist and turn of the deviously complicated plot. Simone Signoret is stunning as one of the victims (an aging actress),the murder scenes are staged in a shivering, cold-blooded manner that must have made Hitchcock green with diabolical envy, and the cast is superlative (keep an eye on a young Jean-Louis Trintignant--he's not at all what he initially seems). The climax (with Perrin trapped in a drugstore pay-phone booth, with Montand on the other end of the line instructing him how to dodge the killers closing in on him) is as heart-pounding, terrifying a sequence ever committed to celluloid. Filmed in France, utilizing breathtaking CinemaScope and black-and-white photography, "The Sleeping Car Murders" was dubbed for its American release. Purists may quibble, but no matter. It remains one of the most hypnotic, audacious (the homosexual twist at the finale was a true audience shocker in '65, and still is)),frightening thrillers ever committed to celluloid. A one-of-a-kind classic--sadly unavailable on DVD, VHS, or cable.

Please let's get "The Sleeping Car Murders" back on the tracks. It's a rare must-see, for thriller-and-movie-buffs alike.

Six people on a Marseilles-Paris sleeper carriage. One murder on arrival. Then a killing spree by an unknown assassin bent on wiping out all remaining passengers.

The Sleeping Car Murders is a French Hitchcockian thriller. It presents a pretty interesting puzzle to be solved, a mystery with a quite satisfying, clever resolution. In some other ways, aside from the Anglo-American Hitchcock influence it's a movie that also contains elements of the Italian giallo, what with its black gloved killer who prowls around bumping off each subsequent victim. It isn't as violent or salacious as the gialli though but it does have the sense of style associated with them. Although this one has a definite Gallic flavour with its Paris setting. It also has a very cool swinging 60's theme tune which adds to the overall chic value. Its plot is admittedly a little muddled at times and it's not always obvious who is who and what they are up to. But things do become clearer as the flick proceeds. It's certainly an interesting obscurity and should be of value for fans of post-noir. Look out too for an appearance by a young Jean-Louis Trintignant.

"The Sleeping Car Murders" is a quintessential and bona fide and prototypic Giallo, and yet at the same time … NOT a Giallo at all. Gialli are – generally speaking – Italian productions from the early 70's with a script written directly for the screen. "The Sleeping Car Murders" is French, released during the mid 60's (when Mario Bava only just kick-started the Giallo concept in Italy) and the script was adapted from a novel by Sébastien Japristot. Surely both Japristot and director Costa-Gavras didn't had a clue what a Giallo in fact was and simply aimed to deliver a good old-fashioned whodunit that would keep the reader/viewer guessing until the very end. Well, the least you could say is … they succeeded! "The Sleeping Car Murders" is an engaging, intelligent and convoluted murder-mystery with a tremendous amount of effective red herrings, detailed character drawings and one perplexedly flawless conclusion. I honestly can't fathom why this movie is so little known, especially since it concerns the writer of "A Very Long Engagement" and the director of the political top thriller "Z". If this exact same story were filmed by, say, Alfred Hitchcock, I bet the film would have ranked high in this website's top 250.

Speaking of Hitchcock; several of his film revolved on the potentially perfect murder plot (like "Strangers on a Train", "Dial M for Murder"…) but – in my humble opinion – this is the film which comes up with the most ideal and waterproof scheme to get away with murder. I've rarely been overwhelmed and impressed as much as when upon witnessing the denouement of "The Sleeping Car Murders". Obviously I can't reveal too much about the climax, but it's so damn great that I really was almost tempted to select some random people and try out the formula myself! Six strangers share a compartment on the night train to Paris, one of them being a fare dodger who met up with a cute young girl in the compartment itself. The next morning one of travelers, a woman, lies murdered in her bed and a hugely complicated police investigation led by the cynical Inspector Graziani ensues. The next following days, however, the other residents of the compartment are murdered – Agatha Christie style - in cold blood as well, as if the killer wants to eliminate all potential witnesses before they have a chance to talk to the police. With the number of compartment survivors rapidly decreasing, the fare dodger and his girlfriend will have to seek protection before the killer finds them.

The set-up of "The Sleeping Car Murders" is brilliant, without any form of exaggeration, and the tight screenplay fills in every tiny detail and remains always several steps ahead of even the cleverest viewers. The plot patiently takes its time to draw a detailed portrait of every witness and, since they each have their own dark secrets and suspicious characteristics, they could all be the culprits. The structure and unfolding of the plot is truly genius here. Whenever you're sure you figured out the killer's identity, he/she gets killed or some other type of twist points out he/she couldn't have done it. The film also gives some marvelous and realistic insight into the progress of a police murder investigation, like stressed Inspectors, false attention-seeking witnesses, dead-end leads, media circuses and a lot of hatred from wrongfully accused suspects. The entire cast and crew also contributes a great deal to the high level of brilliance of the film as well. This may perhaps have been Costa-Gavras' long-feature debut as a director, but his obvious talents and straightforward vision place his right away up there with the greatest film-makers ever. The performances, particularly from Simone Signoret and Yves Montand, are just as top-notch as every other tiniest detail in the rest of this ingenious but shamefully overlooked production.
