Nathalie Ribout, the initial script by Philippe Blasband, was published as a play in 2003 and made it to the stage in Paris in 2009 at the Théâtre Marigny with Virginie Efira as Nathalie and Maruschka Detmers as the wife. The play isn't considered to be an adaptation of the film, but more of a variation on the same idea, as Blasband's original screenplay was significantly reworked for the film, with the couple in Blasband's script being separated and in the midst of divorce proceedings, in addition to being named Sonia and Jean-Luc instead of Catherine and Bernard.
Was released to French theaters exactly one year and one day after the first day of filming.
Vanessa Paradis was initially cast as Nathalie but dropped out due to being pregnant with her second child, Jack Depp.
Gérard Depardieu and Fanny Ardant's third time playing a couple, after La femme d'à côté (1981) and Le colonel Chabert (1994).
