I have a funny relationship with In The West. I think its Leone's best film, in terms of his craft. Yet I like all 3 of the Dollars films more. I attribute it solely to casting. Bronson, Fonda, and Robards dont hold a candle to Eastwood, Wallach, and my boy "Hawk Eyes" Van Cleef in the western genre.
Also Himuro, when you start the movie and think "damn, Ive heard this music a billion times!", remember that this is the film it was written for.
