One of the saddest and most beautiful moments in movie history.  This is the scene from “Blade Runner” where the film’s ostensible “villain” Roy Batty (played by Rutger Hauer) saves the life of the film’s hero Rick Deckard (played by Harrison Ford) and delivers a brief, but moving monologue before dying:

“I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I’ve watched c-beams glitter in the dark near the Tannhäuser Gate. All those … moments will be lost in time, like tears…in rain. Time to die.”
