When You Read This Letter

When You Read This Letter (original title: Quand tu liras cette lettre) is a 1953 French-Italian drama film directed by Jean-Pierre Melville from a screenplay by Jacques Deval. The film stars Philippe Lemaire, Juliette Gréco and Yvonne Sanson.

Running about 120 minutes, the production was filmed at the Billancourt Studios in Paris, with additional location shooting along the coast of Southern France, where the story is set. The sets were designed by art director Robert Gys. The picture proved a commercial success at the box office, and its earnings allowed Melville to acquire his own studios for his future productions, making it a notable turning point in the director's career.
