Quo Vadis (1951 film) in the context of "Peter Ustinov"

Gaius Petronius Arbiter (/pɪˈtroʊniəs/; Classical Latin: [ˈɡaː.i.ʊs pɛˈt̪roː.ni.ʊˈs ar.bɪ.t̪ɛr]; c. 27 – c. 66 AD; sometimes Titus Petronius Niger) was a Roman courtier during the reign of Nero (r. 54–68). He is generally believed to be the author of the Satyricon, a satirical novel believed to have been written during the Neronian era. He is one of the most important characters in Henryk Sienkiewicz' historical novel Quo Vadis (1895). Leo Genn portrays him in the 1951 film of the same name.

Leopold John Genn (/ɡɛn/ GHEN; 9 August 1905 – 26 January 1978) was an English actor and barrister. Distinguished by his relaxed charm and smooth, "black velvet" voice, he had a lengthy career in theatre, film, television and radio, often playing aristocratic or gentlemanly, sophisticated roles.

Born to a Jewish family in London, Genn was educated as a lawyer and was a practising barrister until after World War II, in which he had served in the Royal Artillery as a lieutenant-colonel. He began his acting career at The Old Vic and made his film debut in 1935, starring in a total of 85 screen roles until his death in 1978. For his portrayal of Petronius in the 1951 Hollywood epic Quo Vadis, he received an Oscar nomination for Best Supporting Actor.

Patricia Alice Laffan (19 March 1919 – 10 March 2014) was an English stage, film, television and radio actress, and also, after her retirement from acting, an international fashion impresario. She was five feet, six inches tall, with dark reddish-brown hair and green eyes. She is best known for her film roles as the Empress Poppaea in Quo Vadis (1951) and the alien Nyah in Devil Girl from Mars (1954). Her biography, Devil Girl Remembered, was written by Andrew Ross in 2021.

Sword-and-sandal, also known as peplum (pl.: pepla), is a subgenre of largely Italian-made historical, mythological, or biblical epics mostly set in the Greco-Roman antiquity or the Middle Ages. These films attempted to emulate the big-budget Hollywood historical epics of the time, such as Samson and Delilah (1949), Quo Vadis (1951), The Robe (1953), The Ten Commandments (1956), Ben-Hur (1959), Spartacus (1960), and Cleopatra (1963). These films dominated the Italian film industry from 1958 to 1965, eventually being replaced in 1965 by spaghetti Western and Eurospy films.

The term "peplum" (a Latin word referring to the ancient Greek garment peplos) was introduced by French film critics in the 1960s. The terms "peplum" and "sword-and-sandal" were used in a condescending way by film critics. Later, the terms were embraced by fans of the films, similar to the terms "spaghetti Western" or "shoot-'em-ups". In their English versions, peplum films can be immediately differentiated from their Hollywood counterparts by their use of "clumsy and inadequate" English language dubbing. A 100-minute documentary on the history of Italy's peplum genre was produced and directed by Antonio Avati in 1977 titled Kolossal: i magnifici Macisti (aka Kino Kolossal).

Hollywood on the Tiber is a phrase used to describe the period in the 1950s and 1960s when the Italian capital of Rome emerged as a major location for international filmmaking attracting many foreign productions to the Cinecittà studios. It was used in a June 26, 1950 Time magazine article. By contrast to the native Italian film industry, these movies were made in English for global release. Although the market for many of these films was primarily American, they enjoyed widespread popularity in other countries, including Italy.

The commercial success of Quo Vadis (1951) led to a stream of blockbusters produced in Italy by Hollywood studios, which reached its height with 20th Century Fox's Cleopatra in 1963. The phrase "Hollywood on Tiber", a reference to the river that runs through Rome, was coined in 1950 by Time magazine during the making of Quo Vadis.
