Considered by many to be the first and greatest film of Audrey Hepburn's career.
What is special about this film? Really, little. The story is very simple: it is the almost adolescent escape of a young princess who, tired of the responsibilities and visibility inherent in a crown, decides to distract herself and live her youth for a few hours. The problem is that she ends up, inadvertently, at the home of an American news journalist in charge of interviewing her, and who wants to take advantage of the situation. Of course, anyone hoping for an interesting dalliance between the princess and the commoner will be rewarded, to some extent. Predictable? Cliché? Of course, but it was with illusions like these that cinema fed the magic of the monarchical universe, somewhat to its own advantage.
If the story told is not particularly brilliant and stands out for its simplicity and a range of obvious choices and solutions, what are we left with? Scenarios? Costumes? Effects? Sound? Cinematography? In part, yes. The sets are very well done, and the film, which is actually filmed in Rome, is one of the first and best cinema postcards of this city. I still know people who have been to Rome, and been where the characters in the film have been too, such as the Trevi Fountain or the Mouth of the Truth, tourist landmarks that this film helped to popularize. Without major effects, it has a nice and atmospheric sound and soundtrack, and the cinematography, in black and white, is very good. The scenes of the two main characters riding a Vespa through the streets of the city center are particularly anthological. We can also say that the film was wonderfully edited, and the story moves at an elegant and pleasant pace.
But what would this movie be without Audrey Hepburn? I don't think it's possible to imagine the character in the skin of another actress. She had the nobility and dignified serenity required of royalty, and imbued the character with authenticity, credibility, and friendliness. It's impossible to watch the film and not feel a certain sympathetic affection for her character, who simply wants a few hours to distract herself from the institutional routines and duties for which she was educated. Gregory Peck was a clear choice to be the journalist who helps her and creates a certain romantic affection for her.
