For a Few Dollars More
Just like Leone's first Western, the following works in his Dollars Trilogy — "For a Few Dollars More" (1965) and "The Good, the Bad and the Ugly" (1966) — strongly influenced the further developments of the genre, as did Sergio Corbucci's "Django" and Enzo Barboni's two Trinity films, as well as some other successful Spaghetti Westerns.
