Roman Holiday is a 1953 American romantic comedy film directed and produced by William Wyler. It stars Audrey Hepburn as a princess out to see Rome on her own and Gregory Peck as a reporter. Hepburn won an Academy Award for Best Actress for her performance; the screenplay and costume design also won. The script was written by John Dighton and Dalton Trumbo, though with Trumbo on the Hollywood blacklist, he did not receive a credit, and Ian McLellan Hunter fronted for him. Trumbo's credit was reinstated when the film was released on DVD in 2003. On December 19, 2011, full credit for Trumbo's work was restored. Blacklisted director Bernard Vorhaus worked on the film as an assistant director under a pseudonym. The film was shot at the Cinecittà studios and on location around Rome during the "Hollywood on the Tiber" era. The film was screened in the 14th Venice Film Festival within the official program. In 1999, Roman Holiday was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Plot Crown princess Ann is on a tightly scheduled tour of European capital cities to promote goodwill and improve trade relations for her unnamed nation. After an especially hard day in Rome her doctor gives her an injection and advises her: "Best thing I know is to do exactly what you wish for a while." When she is left alone she secretly leaves her bedroom and country's embassy to witness city life. The effect of the drug then sets in, and she ends up happily lying on a stone bench. Joe Bradley, an expatriate reporter for the "American News Service", finds her there without recognizing who she is. He thinks she is intoxicated and, feeling protective, he takes her to his apartment to sleep it off. The next morning, Joe hurries off late to work and gives his editor, Mr. Hennessy, false details of his attendance at the princess's press conference. When Hennessy informs him that the event had been cancelled and shows him a news item about the princess's "sudden illness" with a picture of her in it, he realizes who is asleep in his apartment. Seeing an opportunity, Joe privately calls his photographer friend, Irving Radovich, to get him to secretly take pictures. Joe then tells Hennessy that he will get an exclusive wide-ranging interview
