Vincent Cassel is starring in Yves Saint Laurent's latest fragrance ad as the face of La Nuit de L’Homme. Directed once again by "Black Swan's" Darren Aronofsky, Cassel is shown seducing three beautiful women in Paris. The commercial does a stellar job at capturing the essence of La Nuit de L'Homme which, according to YSL, is "wildly sensual" and "magnetic."
