I just watched this again a couple of weekends ago. It is my favorite non-Spaghetti western.
One of my favorite moments in the film is a brief scene in which Wyatt Earp (Fonda) is standing at the bar in an empty saloon, talking to the bartender (named Joe). He is thinking about Clementine;
Earp (to Joe, the bartender): "You ever been in love Joe?
Joe: "Naw, I've been a bartender all my life."
I used to think that this was the greatest non sequitur in film. It seems so far off that it is almost like a Zen koan. I've often wondered if there was some connection to this comment made by Joe and the ending of the film in which Wyatt decides NOT to stay with Clementine and rides off to attend to other duties.
I looked on youtube to see if they had a clip of this but they do not. But I did see the 'Shakespeare" scene so I have linked to it here. This film is so amazing looking. It's interiors are masterful. This scene demonstrates it:
