The French actor is starring in a new commercial for Yves Saint Laurent's best-selling men's fragrance.
Having fronted the Nuit de l'Homme campaign for two years now, it was Cassel who suggested director Darren Aronofsky, with whom he had already worked on Black Swan, for the ad.
The script for the short film is based on Søren Kierkegaard's The Seducer's Diary and follows a mysterious Cassel around Paris, seducing several women played by models Marine Vacth, Alyssa Ali, and Eniko Mihalik.
The print campaign, which also broke this month, was shot by photographers Mert & Marcus.
