When Ridley Scott’s dystopian neo-noir sci-fi opus opened in 1982, it was overshadowed at the box office – along with a number of other worthy films – by the juggernaut that was Steven Spielberg’s “E.T.: The Extra-Terrestrial.”  Consequently, it was deemed by the then-reigning Hollywood pundits to be a misfire, and critics seemed to echo that sentiment; though praised for its imaginative visual design – now regarded as influential and iconic – and its provocative thematic explorations, it was greeted with middling reviews that, taken together, marked it as an “interesting failure.”

This lukewarm reception came at the end of a tense and difficult production process in which Scott, who had been far down the list of preferred directors for this long-awaited adaptation of Phillip K. Dick’s “Do Androids Dream of Electric Sheep?,” went severely over budget and seriously past due – eventually losing creative control of the final cut and being forced to bow to studio executives’ demands to cut the running time by nearly half and add a voice-over narration to clarify what they felt to be a confusing plot.

Despite its painful birthing process (and perhaps, in part, because of it), “Blade Runner” went on to become a cult favorite, with an ever-growing legion of fans, and to be re-evaluated by critics – even making appearances high on their lists of the best science fiction films of all time.  Ultimately, thanks to its growing reputation, Scott released a series of alternate versions, culminating in “The Final Cut,” released in 2007, which restored several minutes of previously deleted material and dispensed with the much-hated narration, and which stands today as the definitive edition of the film.

To those new to it, “Blade Runner” is essentially a police procedural set in a future Los Angeles.  The title refers to the name given to special officers whose job it is to track down and eliminate “replicants” – artificial humans created as an off-world labor force who are now outlawed on earth.  One such officer, Rick Deckard (Harrison Ford), is tasked with tracking down and killing a renegade group of these beings who have defied the ban to come in search of answers from their creator.  Constructed as a pulp-fiction detective story in the nostalgic vein of Raymond Chandler, the plot winds its morally ambiguous way through a shadowy underworld – replete with femmes fatale, corrupt officials, secret alliances, and deep conspiracies – towards a final showdown that forces Deckard (and the audience) to question what it means to be “human.”

Revisiting this seminal work over three decades later, those who grew up with it may find it challenging to separate its authentic merits from their fond memories; likewise, those new to its affected mix of high-concept style and gritty action may fail to recognize its impact on a genre whose subsequent development owes it so much.  There are also those, in both groups, who might find its slow-moving plot and relative lack of action sequences less appealing than the genre’s bigger, splashier counterparts.

Nevertheless, there are a number of good reasons why “Blade Runner” has had staying power.

To begin with, there’s the incredible, immersive reality that Scott (along with production designer Laurence G. Paull and special effects supervisor Douglas Trumball) so painstakingly assembled to represent the Los Angeles of then-distant 2019.  Densely overpopulated with an ethnic blend of citizens (predominantly of Asian descent), lit by garish neon, and dominated by advertisements projected at massive scale in every available space, it’s a claustrophobic metropolis that is at once dazzlingly futuristic and depressingly familiar – the logical extension of corporate consumerism run wild and rampant urban decay left unchecked.  Though the causes for this state of affairs are never specifically addressed within the dialogue, the world of the film needs no words to express the volumes of social criticism inherent in its design.  It’s a magnificent example of one of science fiction’s primary functions – to serve as a warning against the worst tendencies of our own world – executed to perfection, and it has justly become a blueprint for world-building in countless films within the genre, ever since.

Then there’s the way it addresses the subject of artificial intelligence.  “Blade Runner” was certainly not the first movie to introduce the notion of an A.I. becoming sentient or developing emotion, but in its deeply philosophical treatment of the idea – and its portraits of its remarkable anti-hero, Roy Batty (Rutger Hauer) and his sidekick/lover, Pris (Daryl Hannah) – it goes beyond the usual cautionary approach to address the ethical dilemmas presented by drawing a line between human and non-human life.  These characters are vicious, violent, cruel – but they are not unsympathetic, nor are they without justification.  Rather, their behavior is easily understood as the result of exploitation, mistreatment, and disregard by a system that presumes their lives have no inherent value.  That they rebel against their oppressors is not only understandable, it is unsurprising; and the fact that, in their suffering, they have developed a sense of loyalty to each other and empathy towards others (whether or not they are governed by it) places them in stark contrast to most of the “human” characters we see in the film.  This concept of the misunderstood creation at odds with its creator hearkens back, of course, to that ancestor of all modern sci-fi stories, Mary Shelley’s “Frankenstein,” but by placing it in the context of this grimly foreseeable future, “Blade Runner” reminds us that the questions it raises are perhaps more relevant than ever.

There are many other factors that contribute to the film’s lasting impact.  The commitment to its noir milieu is not only consistent, but brilliantly apt for a story set within this world of shadows (both actual and metaphorical), and the way this cinematic conceit is meshed with the stylish visual influences of the era in which it was conceived is, at times, breathtakingly artful.  Electronic composer Vangelis envelops the action (and the audience) with his lush, moody, and elegiac score, which evokes the epic scope of both the story’s setting and its philosophical ambitions.  Perhaps most importantly, the screenplay, by Hampton Fancher and David Webb Peoples, provides a solid base for the entire package; it weaves complex ideas and implications into a story which both expands upon the source material and remains essentially faithful to it, and it does so through dialogue which echoes the hard-boiled style of the cinematic movement to which it pays homage.

Of course there are also the performances.  Ford, fresh from his first appearance as Indiana Jones in “Raiders of the Lost Ark” and in between his second and third turns as Han Solo in the original “Star Wars” trilogy, was at the peak of his appeal and popularity when he stepped into the title role of Scott’s movie (thought he, like the director, was nowhere near the first choice for the project); though at first his cocky persona seems somehow out of joint with the dreary world portrayed here, it is this that makes him a perfect fit for a character whose experiences will awaken the humanity buried beneath his cynical exterior.  Deckard is the direct extension of every smart-ass gumshoe portrayed by Humphrey Bogart in the classic film noir of the forties and fifties, and Ford – who rarely gets the credit he deserves for his acting skills – brings that same diamond-in-the-rough essence to the role.  His performance here may not be as iconic as the ones that cemented his status as one of his generation’s biggest stars, but it is just as engaging – and considering the complexity of Deckard’s emotional journey, maybe more impressive.

Sean Young, another star whose acting talents are often overlooked (particularly in the wake of the career-stifling reputation she earned – fairly or unfairly – in the years following her appearance here), is equally well-matched to her role.  More than just a love interest provided to add obligatory romance to the plot, Rachael turns out to be an important element in the film’s brooding meditation on the nature of sentience and humanity; revealed early on to be an advanced replicant herself, the attraction she shares with Deckard becomes central to the self-discovery that parallels his investigations, and much of what makes it believable comes from Young – ethereal yet grounded, distant yet warm, fragile yet confident, she provides a perfect complement to Ford’s energy and gives their pairing a resonance that reinforces its ultimate significance to the larger saga.  She deserves as much credit for the depth of her performance as she does for the stunning beauty she brings to the screen – particularly in her signature look, the forties high-fashion ensemble she wears in her early scenes, which has become emblematic of the film.

As Batty, the replicant ringleader bent on confronting the man who made him, Hauer – previously acclaimed in his native Netherlands – became an American movie star in his own right; his intelligence, intensity, and charisma burns from the screen, putting the audience on his character’s side from his first entrance despite the seemingly thoughtless brutality of his actions.  His climactic confrontation with Deckard, which ends in the sort of Messianic epiphany that might be a difficult sell for many actors, is electric – a powerfully moving star turn that gives “Blade Runner” its greatest weight and ensures its status as a work above the level of many more ambitious science fiction dramas than this one.

Another star-making performance comes from Hannah, whose portrayal of Pris – less advanced than her cohort Batty, but every bit as remarkable – conveys the perfect combination of little-girl-lost naïveté and subtly gleeful sadism, making her as appealing as she is lethal.  As the other two replicants on the lam, Brion James and Joanna Cassidy each have unforgettable scenes of their own.

William Sanderson is heartbreaking as the haplessly unwitting ally enlisted to aid and abet the fugitives in their quest for answers.  Joseph Turkel (as Eldon Tyrell, the powerful genius behind the creation of artificial humans) captures the aloof benevolence of the untouchable elite; a major player in two of the film’s key scenes, his performance makes them all the more memorable.

Though his role is a small one, Edward James Olmos also makes a deep impression as Gaff, the police lackey who serves as a watchdog for the chief (M. Emmett Walsh, also memorable, as always); speaking mostly in a hybrid street slang – derived from different Asian languages – and occupying his hands by making origami figures that provide mocking commentary of Deckard, his sinister presence exudes the hunger of a jackal waiting for its opportunity to pounce – yet he remains inscrutable enough for us to believe that he just might, in the end, turn out to be an unexpected ally.

Whether or not he does, of course, is one of the most enduring questions generated by “Blade Runner” – alongside the possibly related one of whether or not Deckard himself may unknowingly be a replicant.  The answers to those, and myriad others which arise within this unlikely jewel of eighties popular cinema, are ultimately left to the viewer.  This tantalizing ambiguity leaves us, like Batty and his cadre of artificial soul-seekers, with a powerful yearning that has proven strong enough to justify a sequel, 35 years later.

It’s also what has ultimately made Scott’s “interesting failure” an enduring legend that can stand alongside- and, in most cases, overshadow – many of the better-received films of its era.
