Roman Holiday has a simple plot, but it has become a world classic with the successful performances of the hero and heroine and the street view of Rome, especially Audrey Hepburn, whose charm has captivated countless fans and her lovely Hepburn hairstyle has been immortal. The film vividly integrated the sights of Rome into the plot and produced a very warm and pleasing romantic comedy. Two people, one is tired of boring and complicated court etiquette, and the other is a little reporter with little money in his pocket. Although the days in Rome were short, the relaxed and comfortable time made them feel the sweetness of love. Although they didn't come together because of their respective identities and responsibilities, Rome became a symbol of their eternal love.
