The ''"Dollars Trilogy"'' (also known as ''"[[TheTropeWithoutATitle The Man with No Name]] Trilogy"'') is a trilogy of SpaghettiWestern films by Creator/SergioLeone. It consists of, in order of production:
* ''Film/AFistfulOfDollars''
* ''Film/ForAFewDollarsMore''
* ''Film/TheGoodTheBadAndTheUgly''.

They are tied together by the following things:

# Directed and co-written by Creator/SergioLeone.
# A soundtrack composed by Music/EnnioMorricone.
# Being Westerns filmed far from America -- in UsefulNotes/{{Spain}}, since it has more WildWest-type terrain than Leone's native UsefulNotes/{{Italy}} does.
# Creator/ClintEastwood is in all of them, popularly referred to as the Man With No Name. Although he is referred to by a different name in each film ("Joe", "Manco", and "Blondie" respectively), all of them are nicknames given to him by another character, and it's unclear whether he is even supposed to be the same character, at least until he picks up the poncho he wears in the other two films towards the end of ''The Good, The Bad and the Ugly''.
# It also features Leone's regular cast members consisting of the likes of Aldo Sambrell, Benito Stefanelli, Lorenzo Robeldo and Mario Brega, and both Creator/LeeVanCleef and Gian Maria Volonte appear in two films.
# It spawned a series of five tie-in novels: ''A Coffin Full of Dollars'', ''A Dollar to Die For'', ''The Million Dollar Bloodhunt'', ''Blood For a Dirty Dollar'' and ''The Devil's Dollar Sign'', as well as {{Novelization}}s of the films themselves.

The ''"Dollars Trilogy"'' is simultaneously a ThematicSeries (there are no story connections at all and only some cursory ContinuityNod moments) and a DeconstructorFleet. Together, they tell how the West was tamed, and where Men with No Name fit in all of that.

This series ended BlackAndWhiteMorality in later Westerns. It also made everyone who made Westerns after these films want to cast Creator/ClintEastwood.
