The alternate English title for Grémillon’s film, “The Woman Who Dared,” suggests the political message the director was aiming at the citizens of an occupied, wartime France. Based on a true account from the 1930s, the story concerns an ordinary woman who overcomes the pettiness of provincial views to break the women’s world distance-flying record, with the aid of her mechanic husband. This radiant and empowering masterpiece is less about aviation than about the average Frenchman’s (and, indeed, Frenchwoman’s) wartime potential. But for the disorganization of the French film industry in the late wartime years, Le ciel est à vous, with its with beautiful and direct imagery, might have become the seminal film of a French neorealism movement.
