The series was initially developed for channel Canal+, first as six hour long episodes, then as twelve half-hour episodes, before being picked up by Arte as nine half-hour episodes.
Initially slated for Spring 2020, filming was pushed back to October due to the COVID-19 pandemic.
Emmanuelle, George and Gabrielle are 44 year old triplets in the series. In real life, Virginie Ledoyen did celebrate her 44th birthday during filming, while Valérie Donzelli was 47 and Virginie Ledoyen was 41.
