I've watched For a Fistull of Dollars, For a Few Dollars More, The Good the Bad and the Ugly, Once Upon a Time in the West and For a Fistfull of Dynamite, all from Sergio Leone and with music from Ennio Morricone.
I find For a Fistfull of Dynamite a great movie. Underestimate, but good. The discussion about what really is the revolution and who pays the price is worth the entire movie. And the music...wow
