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 name was reinstated when the film was released on DVD in 2003, and 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". The film has been considered one of the most romantic films in cinema history.
