Blade Runner: The Director’s Cut (1982) is the only version of this film I’ve seen, so I have no real idea what the original theatrical movie was like. On Amazon, I found this explanation:
When Ridley Scott’s cut of Blade Runner was finally released in 1993, one had to wonder why the studio hadn’t done it right the first time–11 years earlier. This version is so much better, mostly because of what’s been eliminated (the ludicrous and redundant voice-over narration and the phony happy ending) rather than what’s been added (a bit more character development and a brief unicorn dream). Star Harrison Ford originally recorded the narration under duress at the insistence of Warner Bros. executives who thought the story needed further “explanation”; he later confessed that he thought if he did it badly they wouldn’t use it. (Moral: Never overestimate the taste of movie executives.) The movie’s spectacular futuristic vision of Los Angeles–a perpetually dark and rainy metropolis that’s the nightmare antithesis of “Sunny Southern California”–is still its most seductive feature, an otherworldly atmosphere in which you can immerse yourself. The movie’s shadowy visual style, along with its classic private-detective/murder-mystery plot line (with Ford on the trail of a murderous android, or “replicant”), makes Blade Runner one of the few science fiction pictures to legitimately claim a place in the film noir tradition. And, as in the best noir, the sleuth discovers a whole lot more (about himself and the people he encounters) than he anticipates…. With Sean Young, Edward James Olmos, Daryl Hannah, Rutger Hauer, and M. Emmet Walsh. –Jim Emerson
I first watched this DVD (the director’s cut, as explained above, was released eleven years after the original) years ago, and found certain sequences so violent, that I haven’t had the nerve to view it since. However with the recent death of actor Rutger Hauer (who was so good in so many different roles) who played replicant Roy Batty, I felt compelled to borrow the disc back from my son.
