Leon shoots Holden as he administers the Voight-Kampff test on him at Tyrell Corporation. He later attacks Deckard but is himself killed by Rachael who shoots him with Deckard's gun.

The Snake Pit Bar features music, exotic dancing, and something being smoked in pipes. When Deckard interrogates Taffey about his use of artificial snakes, Taffey dismisses Deckard's question with a free drink.

She gets a job as an exotic dancer at The Snake Pit, creating an act using her own pet snake, but Deckard tracks her down after finding artificial snake scales.

In the final showdown, Deckard is defeated. But just as he's about to fall to his death, Roy pulls him to safety. The replicant is facing a system shut down as his four-year life span is at an end. Does he spare Deckard out of compassion, having finally learned what it is to be human ... or is Deckard perhaps a replicant himself?

Rutger Hauer, who played Roy, improvised the now-iconic line "All those moments will be lost in time ... like tears in rain". He later chose "All those moments" as the title of his autobiography.

In the director's cut, a scene is added where Deckard dreams of a unicorn galloping in the woods. Deckard never tells anyone about the unicorn, but when he leaves his apartment with Rachael at the end of the film, she knocks over an origami unicorn--the last of a series of origami figures made by Gaff, a veteran Blade Runner played by Edward James Olmos, who seems to know more than he lets on.

Living up to the company's motto, "More Human Than Human", Replicants were virtually indistinguishable from human beings.
