Director - Ridley Scott

As ex-blade runner Rick Deckard (Harrison Ford) attempts to "retire" the replicant known as Roy Batty (Rutger Hauer), he finds himself in a precarious position. The battle worn replicant shows mercy on Deckard rescuing him from the edge of the building - only to "die" shortly after giving a moving monologue.
As he reminisces about his past he says, "All those moments will be lost in time...," but then Hauer adds the unscripted and philosophical phrase "...like tears in rain."
