Rick Blaine and Ilsa Lund from 'Casablanca' (1942)
Rick (Humphrey Bogart) and Ilsa (Ingrid Bergman) not only experience love at first sight, but they do it with such style! Such class! They are both beautiful, idealistic, altruistic, ready to risk all for love, even if it can't last. Add the fantastic score as a backdrop and those famous, swoon-worthy lines—from Rick: "Of all the gin joints in all the towns in all the world she walks into mine"; and Ilsa: "Kiss me. Kiss me as though it were the last time"—you can't help but sigh over them.
