A princess named "Ann," portrayed by Audrey Hepburn, finds herself on a whirlwind European journey that includes a stop in Rome. After being put to bed, she impulsively decides to dress down and explore the city on her own. I initially anticipated a romance with a stereotypical charming rogue, but instead, she encounters Gregory Peck, who embodies the image of an average man. Still under the influence of medication given to her beforehand, she winds up staying at his apartment, and he soon discovers her identity – along with the fact that his editor wants a scoop on her visit. With very little money, she attempts to return home but predictably runs into "Joe" again. Along with his photographer friend, Irving (Eddie Albert), they find themselves in amusing and lively situations throughout Rome as this sheltered young woman experiences a brief taste of freedom – even getting a haircut – before the constraints of her life begin to reassert themselves. Hepburn and Peck share undeniable chemistry; the story and the circumstances allow us to witness their growing affection for each other. There's an appealing naiveté in Hepburn’s acting, successfully communicating the feeling of someone who is temporarily liberated but aware that it won't last forever. The interactions with Peck and Albert are also enjoyable as their clever schemes keep getting changed. Georges Auric’s music is sophisticated and playful, and the film's overall stylish presentation makes it a truly pleasant viewing experience. It exemplifies how quality can be achieved through simplicity.
