Thomas Laroppe (Brodeuses (2004) by 'Eleonore Faucher') was first considered for the leading role of Ludovic but he happened not to be available for the shooting dates.
In spite of the tatty aspect of the room, the shooting took place in a three-star hotel of Lyon. On the first day of shooting, all of the original luxurious furnishing of the room (except the bed) have been removed and replaced by old and rickety pieces of furniture sometimes picked and found amongst garbage. The immaculate white walls have been soiled with very liquid mud that gave them this darker shade of beige. For the bathroom, the production designer used a combination of earth and beer so that the soiling ( once dried up) stays stuck on the wall tiling.
Director Frédéric Chane-son was absolutely fond of one of the pieces of decoration, the framed red deer canvas, to such an extent that he took it home at the end of the shooting.
Lamya's zebra-striped high heels were actually too small for Franck's feet to fit in. As a result it finally was up to cinematographer 'David Jacques' to foot double Franck's feet during the close-up shot on the footbridge.
"Les promesses de l'aube" was originally a small part of a feature film screenplay by Frédéric Chane-son called "Une rencontre".
