I can think of no other director at the time with the exception perhaps of Julien Duvivier, who would have dared to make this film other than the 'bourgeois anarchiste' Claude Autant-Lara.
The subject of black market profiteering during the Occupation together with the suggestion that French resistance was anything but unified was strictly taboo but its hard-hitting honesty struck a chord with Gallic audiences and the film was a huge success. Even the arrogant young critic of Cahiers du Cinéma, Francois Truffaut, one of this director's staunchest detractors, was surprisingly full of praise, citing the film's 'insistent ferocity.'
The black market is matched by the black humour of the screenplay by Pierre Bost and Jean Aurenche, adapted from Marcel Aymé's story. Even Autant-Lara could only go so far however and the original story's grim ending has been changed to one that is far happier.
The popularity of the film must surely lie in Autant-Lara's casting of the two protagonists Jean Gabin and Bourvil. This was their only film together and the pairing is inspired. Bourvil's innate naiveté contrasts with Gabin's world-weary cynicism and their artistry is superlative.
The film is also of great interest technically as the pair's eight kilometre curfew-defying odyssey across Paris carrying four cases stuffed full of black market pork, is filmed almost entirely in the studio but this works courtesy of Max Douy's sets and Jacques Nattier's 'noirish' lighting. Indeed the lighting of the scene where Martin and Grangil are arrested reminds one very much of German Expressionism.
There are no heroes here, just fallible human beings with all their vices and virtues, trying to survive as best they can. Everyone has to eat after all and as George Bernard Shaw observed: "There is no love more sincere than the love of food'.
