You mean the entrance of Cheyenne's gang is a reference to that scene?
The Gunfighter, starring Gregory Peck, was cited in an article I once read. This claimed that the scene in which Frank left the saloon, with a gunfight inevitable, was reminiscent of Jimmy Ringo leaving his saloon.
This thread really should be stickied. You guys did a wonderful job, even got that dialogue sequence from Jubal (I was going to suggest it), very impressive. The only thing I would add is Vera Miles' stepping off the train in Liberty Valance is very similar to Jill's in West. I believe I posted this before but I don't even know if it's important enough.
As I said above, I also think that this could be in part of the fact that Leone cited "Warlock" as one of his favorite films. While the "Liberty Valance" references, as relatively vague as they are, can be pretty well confirmed, I see virtually nothing to connect "Warlock" to OUATITW, except that Leone was a fan. So, go figure.
Just saw another possible reference last night a modern day Western film starring Kirk Douglas called "Ace in The Hole", its about a down and out washed up newspaper reporter who is towed in his broken down convertible into Albuquerque, New Mexico. He goes into a local newspaper office to look for a job as a reporter. When he meets the editor he sees that he's wearing a belt & suspenders and Douglas makes the comment (similar to Fonda's in OUTITW) to the editor about him not trusting anything. Story is about a man trapped in a cave and Douglas manufactures the story to get back into the big time, it was a pretty good flick.
"Ace in the Hole" is also known as "The Big Carnival". I've seen it, it's good, and thought provoking.
could been a classic if it had someone other than Kirk Douglas in the lead. Felt like I was watching a Frank Gorshin imitation!
