The flash mob scene was filmed on October 16, 2006. On that date more than four hundred extras get naked all together on the bridge of Castel Sant'Angelo in the center of Rome and dance to the notes of Let the sunshine.
Carolina Crescentini said she felt embarrassed in the scene where she dives into the pool completely naked. She said she was helped by Nicolas Vaporidis, with whom she had great complicity especially during the sex scene. The most embarrassing moment for Carolina, however, was the one in which her father called her a few days after the release of the film. "With the utmost candor he says to me: 'Oh Carolina, my lawyer friend called me, he saw the film, he congratulates you so much!' Here, at the thought that my father's colleagues have seen me naked, I would sink!" said the actress.
