In a scene, Daniel Auteuil introduces his fingers into the vagina of the character of Isild Le Besco, doubled by a pornographic actress. Benoît Jacquot was insisting that they film the real penetration, so he decided, with Auteuil and the producer Patrick Godeau, to bring in a porn actor and actress to use as body double. After reflection, Auteuil said not to stick to it - it is therefore his fingers which penetrates the vagina of Isild Le Besco's double.
In her book 'Dire vrai', Isild Le Besco talked about her nude scene in this movie when she was 17. "Benoît [Jacquot] was obsessed with seeing me naked, lying down, facing the camera. I didn't want it and had announced it from the start. He swore to me that we would shoot with a small crew and that we wouldn't see anything on camera. I felt indebted: I had the feeling that refusing would be a betrayal, while he had trusted me from the start. I gave in. I was simply there to serve his film, after all. My perception of limits was blurred. I was becoming his artistic object, an extension of him. The weekend before the shooting of this scene, Benoît gave me his credit card. He specified that I was free to buy whatever I wanted with it. A credit card against my teenage body and, above all, the surpassing of my limits," she wrote.
