Has some Cyborg in it as well...
Take The Good, the Bad and the Ugly + Night of the Living Dead + Cyborg, you know? The JCVD 80's film? And you get The Quick and the Undead.
I finally got around to watching it and its not as bad as people make it out to be. True, the story was weak and the characters could've been fleshed out a bit more. But for $100,000 this looks pretty sweet. It definitely is a welcome addition to my horror/western collection. Now if only they could pull off a sequel (or remake) with a better script.
