This was originally written with a father/son acting team in mind. The roles were offered to a pair of actors, but they turned the roles down. Around the same time, Laura Smet had learned about this new series and asked her godfather - series producer Dominique Besnehard - if she could appear on an episode. The roles were changed to a mother/daughter acting team, and Laura Smet convinced her mother Nathalie Baye to participate.
Though Dominique Besnehard is credited as playing a character named Paul Granier, he actually seems to be playing himself and is even called Dominique on phone by Mathias Barneville.
When Dominique Besnehard was younger, she interned at the same agency where her godfather - series producer Dominique Besnehard - worked.
