Harrison Ford is Deckard (Blade Runner) who is tasked with finding and eliminating a group of synthetic humans led by Roy Batty (Rutger Hauer).
Ending--
(Deckard hangs by his fingers from a girder off the side of a building. Roy stands above him watching. They are hundreds of stories above the streets. It's raining heavily and Deckard is slowly losing his grip on the edge of the beam.)
Roy: Quite an experience to live in fear, isn't it? That's what it is to be a slave.
(Just as Deckard's hand slips and he starts to fall to his death, Roy grabs his hand and lifts him to safety. Deckard is dropped on the roof. Wounded and exhausted he scurries backward on all fours away from Roy until his rearward movement is halted by a piece of heavy machinery. Roy calmly approaches Deckard and crouches in front of him.)
Roy: 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.
(Roy lowers his head... Roy remains in this position, head lowered, crouching in front of Deckard. Rain streams over his head and unmoving shoulders.)
Deckard: [voiceover] I don't know why he saved my life. Maybe in those last moments he loved life more than he ever had before. Not just his life... anybody's life... my life. All he'd wanted was the same answers the rest of us want. Where do I come from? Where am I going? How long have I got? All I could do is sit there and watch him die.
I remember Harison Ford's voice over narration. The director's cut removed it and used a slightly different ending. Check it out.
