The Man with No Name Rides to Dynamite by Laura Hudson. I may have to make the effort to check this out. Mind you, I'm ambivalent about it, Leone being gone and me being one who leans against the Eastwood characters in those three movies being literally the same character, as noted in Joe.
I'm also terribly confused about the fact that the brilliant and underrated Duck, You Sucker! is out on DVD, but none of my rental outlets, including Netflix, seems to have available.
