The screenplay was inspired by the life story of Florence Foster Jenkins, an eccentric American amateur operatic soprano who stubbornly followed her dream to become a star. Although she had no ear for music; with little sense of pitch or rhythm, the notorious socialite could not be dissuaded by her husband or friends. She fulfilled a lifelong dream performing to a full house at Carnegie Hall in New York.

Catherine Frot (The Dinner Game, 1998; The Page Turner, 2006) is cast as Marguerite, the supporting cast features André Marcon, Christa Théret, Denis Mpungu and Michel Féau.

“The crew began a scheduled 49-day shoot in the Czech Republic on 15 September 2014. Of the film’s total budget of 220 million crowns, 80 million is earmarked for local production costs. Filming takes place mainly in Prague, specifically inside the Vinohrady Theatre and Charles University’s Faculty of Law. Locations outside of the capital include the Slapy Chateau in central Bohemia and the Mahen Theatre in Brno,“ said Nela Cajthlamlová from the Czech Film Commission.

The film is produced by French Fidélité Films and coproduced by Belgium's Scope Pictures and Sirena Film - the line producer on the Czech side (which facilitated the filming of the historical drama A Royal Affair, 2012). The Czech production designer Martin Kurel is part of the main crew of the film. The distribution company is Memento Films of France.
