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:
!!They are tied together by these things:
# Directed and co-written by Creator/SergioLeone.
# A soundtrack composed by Music/EnnioMorricone.
# Being Westerns filmed far from America -- in Spain, since it has more WildWest-type terrain than 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).
The Dollars Trilogy is simultaneously a ThematicSeries (there are no story connections at all) 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.
