You know the Criterion cover for MDC is the shot of Wyatt watching the street, sitting in that chair with his legs kicked up against a support beam? That shot was referenced in all the other movies I watched, IIRC. Was it iconic or something?
The Chihuahua stuff though, psssht. Just plain didn't hold my interest. I don't have much to say about why.
Victor Mature, haven't seen him in anything else, but his Doc is kind of a weepy drunk...gimme any other Doc, maybe even Stacy Keach's 1971 "Doc."
Oh yeah, Walter Brennan, surprisingly menacing as Pa Clanton...who, uh, wasn't at the shootout at the OK Corral, depicted as taking place outside the city limits, duhrrr. I should have mentioned him, since this isn't his usual character at all! Good ole print the legend--I'm sure you're well aware that the shootout took place NEAR the corral and not at it. Of course, more and more stories about the gunfight and various accounts kept spilling out after Earp died in 1929.
(Most depictions of the OK Corral, even the Star Trek depiction, have a big fat obvious sign reading "OK CORRAL," and only I think in Tombstone did they have the one that looks like the one in the actual photograph of the Corral after it burned down in 1882.)
