Cinecittà in the context of "Spaghetti Western"

Gangs of New York is a 2002 epic historical drama film directed by Martin Scorsese and written by Jay Cocks, Steven Zaillian, and Kenneth Lonergan, based on Herbert Asbury's 1928 book The Gangs of New York. The film stars Leonardo DiCaprio, Daniel Day-Lewis, and Cameron Diaz, along with Jim Broadbent, John C. Reilly, Henry Thomas and Brendan Gleeson in supporting roles. The film also marks the start of a collaboration between DiCaprio and Scorsese.

The film is set from 1862 to 1863, when a long-running Catholic–Protestant feud erupts into violence, just as an Irish immigrant group is protesting the threat of conscription during the Civil War. Scorsese spent 20 years developing the project until Miramax Films acquired it in 1999. Principal photography took place in Cinecittà Studios in Rome, and Long Island City, New York City.

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.
