You list John Wayne as an influence so I have to ask: what are your favourite [John Ford...] westerns?
Hands down, it's The Searchers. It's one of the rare occasions that the Duke gets a chance to play a not-so-nice character. A lot of people dismiss him as an actor because he was so type-cast but movies like the Searchers allowed him to show that he could be much deeper than Rooster Cogburn. For a choice in non-western movies, I'll go with The Quiet Man. Anytime Wayne gets to have Maureen O'Hara with him, the chemistry lights up the screen.
