Pierette (Fanny Ardant) tells Augustine (Isabelle Huppert) that she looks like a woman from one of her romance novels, "La Dame Aux Camélias". Huppert actually played Alphonsine in _Storia vera della signora dalle camelie, La (1980)_, an adaptation of that novel.
Virginie Ledoyen played Suzon who was pregnant, actually was pregnant in real life. Danielle Darrieux made a joke about that saying "Actually it was 'neuf femmes' and not huit".
