Sergio Leone's work with Clint Eastwood changed the landscape of Westerns, as well as the landscape of world cinema. After the overwhelming success of 1964's A Fistful of Dollars, a new subgenre was born: The Spaghetti Western. The resulting films represent a now-gone era of stylish filmmaking.

The Spaghetti Western differentiates itself from traditional Westerns with various quirks and qualities. Spaghetti Westerns were often made in Italy's legendary Cinecittà Studios on a relatively low budget with international crews and performers.
