Potiche is the term used in French slang that means trophy wife.
Catherine Deneuve and Gerard Depardieu worked together in ten films: "Le Dernier métro" (François Truffaut,1980), "Je vous aime" (Claude Berri, 1980), "Le Choix des armes" (Alain Corneau, 1981), "Fort Saganne" (Alain Corneau, 1984), "Drôle d'endroit pour une rencontre" (François Dupeyron, 1988), "Les Cent et une nuits de Simon Cinéma" (Agnès Varda, 1995), "Les Temps qui changent" (André Téchiné, 2004), "Potiche" (François Ozon, 2010), "Astérix et Obélix : Au service de sa majesté" (Laurent Tirard, 2012) and "Bonne Pomme" (Florence Corentin, 2017).
While the film is set in northern France, it was entirely shot in nearby Belgium.
A trailer for this film is used in UK cinemas as part of the "Don't let mobile phones spoil your film" campaign run by the telecoms company Orange. The English subtitles have been replaced with new phone-related dialogue and the music in the disco sequence is replaced with a ringtone version.
At the end of the movie, Catherine Deneuve actually sings "C'est Beau la Vie".
