Moreno then discusses the history of the first film, which earned her an Academy Award for Best Supporting Actress, and relives a moment with Fallon as her dance partner. Fallon closes the conversation with a clip from the new film, in which Moreno's Valentino tells Ansel Elgort's Tony how to romance Maria: "Quiero estar contigo para siempre."
