"Un Papillon Sur L'épaule" is a quiet thriller which depicts why an honest man always gets involved in shady deals. It allows us to question whether it is due to unforeseen circumstances which force an honest man to go astray or is it something in an honest man's disposition that he cannot evade dangers. According to this film,the plight of the honest man is really strange as despite all heroic fights, he is the one who emerges as the ultimate loser. There is hardly anything in his control to change events and circumstances as he is merely a puppet as the strings are with somebody else. In this film, Jacques Deray has made an effective use of dream, hallucination and reality to portray a hapless man whose destiny is crisscrossed by these very elements. Lino Ventura gives a very restrained performance in his role of an ordinary French citizen who loses his life in a hostile Spain.Although actress Nicole Garcia has a very limited role, she manages to garner viewers' sympathy as the wife of a man who directs all possible efforts in rescuing her husband from the clutches of invisible forces.

Although screenwriter Jean-Claude Carriere is best-known for his close association with Luis Bunuel during the last 20 years of the latter's life which produced some of his greatest and best-loved work, he did not work exclusively within art-house circles or with highbrow material. Indeed, he was as prone to adapt for the screen famous literary pieces as he was pulp fiction. In fact, between 1969 and 2001, he worked 11 times with one of French cinema's expert purveyors of crime thrillers, Jacques Deray – although, to be sure, even this significant collaboration included forays into Balzac and Zweig! Anyway, BORSALINO (1970) was Deray's most popular film and that was co-scripted with Carriere as was the star-studded U.S.-based thriller THE OUTSIDE MAN (1972). To counter the cheeky machismo of Jean-Paul Belmondo and the gloomy romanticism of Alain Delon, there came the brooding intelligence and, on occasion, the sheer brute force of Lino Ventura; he had debuted in Jacques Becker's GRISBI (1954) in a supporting role as the villain of the piece but soon graduated to leading roles as the anti-heroic gangster on the run of Claude Sautet's excellent CLASSE TOUS RISQUES aka THE BIG RISK (1960) and the patriotic leader of the French Resistance of Jean-Pierre Melville's marvelous ARMY OF SHADOWS (1969). A measure of the world-weariness of the roles he generally played can be gleaned from the knowledge that, even though he worked and lived for most of his life in France, the Italian-born Ventura never applied for French citizenship! The film under review is a slow-burning but eminently satisfying Kafkaesque thriller with Hitchcockian overtones in which a man (Ventura) disembarks into a Spanish port and, when checking in at his usual hotel, hears some groans coming from the next apartment and gets knocked out cold for trying to be a good Samaritan. He wakes up in a strangely deserted rest home whose only inhabitants seem to be an inquisitive mousey psychiatrist, a flabby janitor and an elderly patient forever speaking to a butterfly on his shoulder which is, Harvey-like, visible only to himself. Returning once again to collect his things from the hotel, he happens to overhear a conversation between the concierge and the dead man's wife (Laura Betti) and, when he offers to help in clearing up the mystery, she is run down by a speeding car – but not before having passed on to Ventura a key to a luggage locker. The "McGuffin" in this case is a suitcase which everybody – from the psychiatrist to the anonymous villains (including the aforementioned janitor) who keep contacting Ventura on the phone and even seemingly sympathetic stranger Claudine Auger – clearly craves and are not above kidnapping Ventura's wife (future director Nicole Garcia) and, ultimately, having him shot by an unseen sniper at the film's very end. Carriere's Bunuelian credentials crop up intermittently during Ventura's hallucinations at the beginning that see him walking down the corridors of the rest-home and pushing the doors open to be met inside by the hotel victim, the butterfly patient and, eventually, himself!

Let me get this straight. I'm a huge Ventura's fan. I love every single movie he's even been in. Every single movie but this one, that is. I've found very frustrating not to understand the first thing about the plot. What is this movie all about? Spies? Secret war? State secrets? Traffic? We have no clue. So you keep watching it, thinking that sooner or later you may have the key to understand why you've stayed this far. Only the key never come, giving the whole movie a sense of emptiness that I've never experiences before. So if you want to lose your time, to feel frustrated and empty, go for it. If you want a head and tail movie though, you'll have to go elsewhere, for there is no such simple thing herein.

The plot outline on the IMDB page is about a "young man" ,which does not exactly describes Lino Ventura who was nearing 60 when this movie was made.This is minor quibble:"Un papillon sur l'épaule" is by far Deray's most ambitious work.A thoroughly abstract thriller,we never know what is all about.There's a search for a mysterious small suitcase ,and the hero seems to be caught in a cobweb,like a Kafka character.The enemy remains invisible ,the screenplay always refers to "they " "them" "the others" "these people".Who are they?Why are they killing? (there are many murders in this movie)What do they want?Actually the subject had already been treated in the past,and with better results.Henri-Georges Clouzot pulled it off brilliantly with his most underrated oeuvre "les espions" (1957,"diabolique" follow-up),and of course,we will not forget Orson Welles' "the trial" (1963).As far directing is concerned,Deray is no match for these two giants.But his attempt is commendable and will reward you more than the Delon/Belmondo cop stories he too often filmed.
