Unforgiven, 1992. This is the best 10 minutes of my favorite movie of all time. The significance of the bottle at the beginning of this scene, combined with Munny's resolute conviction to the memory of his dead wife up until this point, make for pretty intense drama. It's the crescendo of a man who once slayed his inner beast, only to find that it had been festering within him longing to be unleashed.
So what's your favorite movie of all time? And don't give me that Citizen Kane crap because the only ones who really liked that movie were English professors.
