Hollywood on the Tiber is a phrase used in the 1950s and 1960s when the Italian capital of Rome emerged as a major location for international filmmaking attracting a large number of foreign productions to the Cinecittà studios. By contrast to the native Italian film industry , these films were made in English for global release. Although the primary markets for such films were American and British audiences, they enjoyed widespread popularity in other countries, including Italy.
The business success of Quo Vadis (1951) led to a stream of blockbusters Produced in Italy by Hollywood studios , qui atteint height icts with 20th Century Fox ‘s Cleopatra in 1963. The sentence “Hollywood on the Tiber”, a reference to the river That runs through Rome , was coined in 1950 by Time Magazine during the making of Quo Vadis . 
Following World War II , Hollywood studios are increasingly interested in the production of frozen funds (profits from American films which foreign governments barred from export). These films, known as runaway productions , could also benefit from local subsidies . By the early 1950s, some of the largest-budget American films were being shot in European countries, particularly in Britain and Italy.  American companies are working closely on large-scale domestic film industries.
In Italy, the film makers used the vast complex Cinecittà qui HAD-been built in the 1930s by Benito Mussolini ‘s Fascist diet qui Was aiming to rebuild Italian cinema. Following Mussolini’s overthrow in 1943, production at Cinecitta was suspended and no new films were made until 1948. 
Although American companies had shot in Italy before (such as Fox’s 1922 silent Nero and MGM’s 1925 Ben Hur ) the scale of the post-war investment was unprecedented. Many of the movies were sword and sandal epics, often set in Ancient Rome which required large film sets and location filming . Other movies included contemporary-set romances Roman Holiday(1953) and Three Coins in the Fountain (1954). The companies imported actors from a variety of countries (PARTICULARLY Britain and the United States), Who Appeared Alongside Italians Who played Generally smaller, Supporting roles or extras . Sophia Loren was a notable Italian star with an international role .
In 1962 the lengthy and troubled production of Cleopatra brought further media attention to the city. The delays to a spiraling budget, making it the most expensive film ever made at the time. 
Far from leading to a decline in Italian cinema, the industry boomed during the era. In 1960 Italian films outperformed American imports to Italy for the first time since 1946.  However, there was a growing influence of Hollywood-style productions, as popular Italian genres such as the Sword-and-Sandal and Spaghetti Western attempted to imitate successful Hollywood productions. Italian actors and directors often adopted English -sounding names. 
Cinecittà was at the peak of its international fame between the production of Ben Hur and Cleopatra (1958-1960).  As the 1960s drew on, the fashion for classical epics Began to decline Following The business failure of The Fall of the Roman Empire (1964), ALTHOUGH movies in other genres Such As David Lean ‘s Doctor Zhivago (1965) continued to be profitable.
In 2009 a Hollywood film documentary on the Tiber was released. It portrays Cinecittà and the various stars who worked there between 1950 and 1970.
