In the early days of Hollywood, romantic storylines were often simplistic and formulaic. Think of iconic movies like Casablanca (1942) and Roman Holiday (1953), where a dashing hero sweeps a beautiful heroine off her feet. These classic tales of love and sacrifice were often set against a backdrop of war, social class differences, or other external obstacles. The narrative was clear: good girl meets good guy, they fall in love, and live happily ever after.
