Le Jour se lève was released in France in June 1939 and shown in the US the following year. In France, however, the film was banned in 1940 by the Vichy government on the grounds it was demoralizing and had contributed to the nation's defeat. After the war's end, the film was shown again to wide acclaim.
In 1947, it was again suppressed when RKO Radio Pictures wanted to remake the film in Hollywood (as The Long Night). The company acquired the distribution rights of the French film and sought to buy up and destroy every copy of the film that they could obtain. For a time it was feared that that they had been successful and that the film was lost, but it re-appeared in the 1950s and has subsequently stood alongside Les Enfants du paradis as one of the finest achievements of the partnership of Carné and Prévert.
