One that makes me smile is when we watch Indio kill the bounty hunter responsible for his imprisonment:The body is carried out by Indio's mates and if you look to the backwall there is a Virgin Mary statue which seems to point to the right as if telling the procession which way to exit off-stage.Which they do.Ok, perhaps not memorable but an example of Leone's dry wit maybe?(Well, it makes me laugh anyway.)
i like the jailbreak, where manco just calmly dynamites a hole in the cell wall without a word of explanation. he does it so nonchalently it takes a while for the guy in the cell to realise he's being rescued.i think the funiest bit is when mortimer and manco keep ordering the terrified hotel porter to do the opposite to each other, and in the end he just screams, drops the baggage and runs indoors.and of course, the final scene, both the bodycount (22... 27!) and when he finds the money bags, still tangled in the tree and picks them up in a sort of "might as well have this too" fashion.
I have to say one of my favorite moments is a small one, but it's great. It's the man who is getting a shave at the barbershop when the sheriff sticks his head through the window and nods at him at the first of the movie. The man gets up and half of his beard is gone, but he doesn't care, it makes him look more evil. I just think that shows the brilliance of Sergio Leone and the unique quirks of his characters.
The "Let Red Go..." scene... (I love how Manco uses the mirror behind the bar to size up the compition before spinning around and dispatching the henchmen...
