The way in which David Cronenberg employs the thematic of social isolation in his 1981 film Scanners is subtle but effective: By making each of his main characters deal with varying degrees of social isolation, he is able to demonstrate its effects on people. This allows him to put forth very clearly his argument that being highly isolated from other people not only takes a psychological toll on the one who is isolated, but also turns that person into a potentially dangerous threat to the few people that they do encounter. After close study of the numerous cinematic and narrative techniques that Cronenberg employs to state his case about the dangers of social isolation, such as preventing audience alignment by carefully restricting the actors' performances and sexual proclivities, repeatedly tying the characters' status as a scanner and, consequently, as a social misfit, to their careless and aggressively violent behavior, and, most importantly, giving one of the characters the story arc of gradual progression from being a societal derelict who attacks unwitting people in public to a good-intentioned, relatively ethically upstanding person, one begins to recognize that social isolation itself is the primary antagonist of Scanners.
The opening shot of David Cronenberg's Scanners depicts a man entering food court through bright red doors with the words “EMERGENCY EXIT ONLY” scrawled across their length—thus, Cronenberg wastes no time in conveying the message to the audience that something is not quite right about the film's protagonist, Cameron Vale. As the eerily droning score continues to escalate, the ensuing shots reveal Cameron to be wearing a stocking cap and a trench coat, on which he aptly wipes his hand after sneezing. It would not be wholly unreasonable to think that he is perhaps homeless, and he sticks out like a sore thumb. He is seen snatching a cigarette and various food items from unsuspecting patrons' tables until he finally sits at a table where someone has left an unfinished hot dog, across from two women who look at him with contempt.
To further set Cameron apart from all of the other, normal people in the scene, he very noticeable only encounters groups of people sitting at tables as opposed to coming across anyone eating alone in the food court, which suggests that being by oneself in a public space is odd and negative in and of itself. For any audience members who has trouble picking up on subtleties, Cronenberg provides a point-of-view shot from one of the women's perspective accompanied by clearly audible dialogue between the two that consists entirely of statements about how awful and despicable Cameron is for merely being present nearby them—all of which can be read as the Cronenberg directly telling the audience how to feel about the protagonist. As the scene climaxes, Cameron scans one of the women who then falls to the floor, convulsing, and Cronenberg not only fulfills his duty as a horror director to scare the audience—which is enhanced by the striking, bright red ceiling of the food court as well as the escalator and staircase supports of similar hue that are seen in the background of every shot of Cameron—but he also establishes his intention to prevent character attachment so firmly that it is unmistakable.
Stephen Lack's portrayal of Cameron Vale is almost laughably flat, and while his lack of vocal intonation and frequently blank face may seem silly at first, when one takes a second look at what, exactly, Cronenberg is trying to achieve with the character, Lack's choice to play Cameron in such a lifeless manner makes quite a lot of sense. Cameron is unable to emote and this not only complicates the audience's emotional relationship with him on a basic level, but also isolates the character from the viewer because he has such a dry, uninteresting personality. As Kim Obrist says directly to Cameron later in the film, he seems “barely human.”
Cronenberg goes the extra mile in subverting the Hollywood standards of likeable main characters and readily accessible emotional engagement by including absolutely no sexuality in Scanners. This is actually a bit odd for Cronenberg who, in his films that came before and after Scanners, relied heavily on sexuality to express his ideas about technology and society, among other things. While this decision disallowed Cronenberg from startling his audience with his signature bizarre sexual imagery—say, some sort of inter-scanner mindsex—it serves the dual purpose of undermining the audience's desire for sex in their movie-going experiences and by, again, making its main characters seem all the more isolated by denying them the opportunity to take part in an act that is considered normal among the average, productive citizen in today's society.
On a surface-level reading of Scanners, Darryl Revok is the antagonist, and he is certainly the closest thing to a protagonist that takes a physical form. Encounters with Darryl throughout the film are, not incidentally, some of the more disturbing scenes of the film. For example, the audience's introduction to the character is in a scene in which, with his mind, he makes a man's head explode. That scene comes very early in the film, however, and because of the nonchalant way in which he pulls it off, the audience may be reluctant to identify him as the morally bankrupt being that he is later revealed to be. Darryl shows off his off his true colors in the sequential scene, however, both when he subtly forces the doctor to inject himself with the anti-scanning medication Ephemerol and when he causes the death of five more men by crashing a car using his mind and then forcing one of the men who was supposed to be detaining him to shoot his colleagues.
Between the actions of Cameron and Darryl at this point in the film, the audience has been presented a handful of haunting sequences that all revolve around the violent action of scanners so it would be within reason to assume that being a scanner—or a “telepathic curiosity,” as Dr. Ruth terms it—in and of itself necessarily makes one a dangerous and despicable human being. However, yet again, Cronenberg refuses to make things that clear cut.
The existence of Kim Obrist and the group of scanners that she associates with and collectively scans with serves as a perfect counterexample to this sentiment. And the most important aspect of this group is the sole fact that they are a group. Their ways of life are differentiated from those of Cameron and Revok because they generally avoid violent public displays of psychic dominance but, more significantly, that they seem to be constantly surrounded by other scanners. The fact that they congregate regularly helps them maintain their status as ordinary individuals within society and this is what prevents them from lashing out and at unsuspecting strangers.
This point may be more understated than the notion that scanners have the potential for great danger that is established very early on in the film (and continually re-established repeatedly throughout the film's running length) but it is undoubtedly of more import because, when one boils down the sources of good and ill will on both sides of the coin, it becomes clear that isolation is the deciding factor and the actual antagonist of the film. Unfortunately for Kim and company, after the isolated-from-birth Cameron enters the picture, everyone but Kim herself is eventually brutally murdered by Darryl's men. Just before he himself is shot, one of Kim's friends says to Cameron, “Everywhere you go, somebody dies,” and rightly so.
The looming fear throughout Scanners is that Darryl is forming a united army of scanners that will eventually rule the world, and, particularly by the end of the film, this fear turns out to be grounded in reality. However, throughout the movie, there is little evidence that is presented to suggest that any army of substance actually exists; sure, there are numerous heavily armed assassins dispatched by Darryl to dispose of certain people standing in his way, but none of them seem to be actual scanners, or, if they are, then they are highly ineffective at wielding their telepathic weapons. Most importantly, Darryl is never seen physically associating with these thugs, and they are presumably just hired muscle.
Judging by the sheer number of scanners that Darryl kills or has killed throughout the narrative, he seems to be relying very heavily on the future generation of scanners that he has been planting inside the wombs of unsuspecting women. The problem is that Darryl has apparently not taken into account the fact that he will have to interact on a human level with these new scanners in order to convince them to join his cause, and the reason that is a problem is that his social skills leave something to be desired, more than likely due to his limited social interaction over many years, along with the possibility that surrounding himself with so many people of his own kind just might soften him up slightly, and that could potentially put a damper on his motivation to take over the world.
One can assume this based on the character arc of Cameron that, although seemingly negligible, definitely exists. In the beginning of the film, Cameron is presented as a dangerous character when he causes a rude woman to fall onto the ground in a convulsive fit. However, the fact Cameron himself seems as surprised by his own actions as the people who witness the event sets the stage for his confused intentions perfectly. Past the opening scene, virtually all of the instances of Cameron's use of his scanning powers are either in self-defense (e.g. when he fends off Darryl's armed assassins inside of Benjamin Pierce's house) or situations that are seemingly justified by the pursuit of the greater good (e.g. when he kills at least one person and destroys a great deal of property by attempting to hack Darryl's computer systems via telephone). The primary exception to this comes about a half hour into the film, when Cameron demonstrates his powers against the old “yoga master” Dieter Tautz.
Dieter is presented as a mentally strong but somewhat physically frail person who elicits a fair deal of pathos when he is utterly dominated by Cameron's scan. The way the scan ends is the most important aspect, however: after Cameron brings Dieter's heart rate up to dangerous levels (or at least levels too high for Dieter to deal with), Dr. Ruth verbally commands Cameron to end his scan multiple times, but Cameron does not, either because he is cruel or because he is helplessly entranced by this display of his own power. It all comes down to one look on Cameron's face right after he eventually ends his scan. Granted, there are many odd facial expressions throughout Scanners (especially when someone is either scanning or being scanned) but this one look alone holds thematic and narrative significance, despite its extreme subtlety.
When it seems to Dr. Ruth that Cameron has no intention of complying with his pleas to let up on the struggling Dieter, he pulls out a syringe and a bottle of Ephemerol and, just before he injects it into Cameron's hand, Cameron grabs his hand to stop him from following through. Perhaps he simply did not want to experience the poke of the needle, but Cameron would have been able to see Dr. Ruth only out of his peripheral vision, and if he was truly in a telepathic trance, then he would likely not have been so quick to react to Dr. Ruth's movements. Also, the expression of simple acknowledgment on Cameron's face just thereafter strongly suggests that he was, in fact, fully cognizant of his actions the entire time and was intentionally causing harm to Dieter. Cameron seems content with himself after he sees what he has done, as he matter-of-factly affirms, “You were right, Dr. Ruth; it was easy.”
It is important to remember that, in this instance, Cameron was still recovering from roughly 35 years of intense isolation, having been discovered by Dr. Ruth mere days prior. This detail validates the idea that Cameron becomes a less broadly aggressive and more morally upright person as he begins to integrate himself within society. And this strengthens the notion that, more than anything else, the degree to which one is socially isolated is the ultimate determiner of that person's capacity for violence and aggression, as well as that person's ethical fortitude, at least according to Cronenberg.
David Cronenberg deals with isolation and its negative effects on people in several of his works, including two of his more notable films that followed Scanners: those who isolate themselves in 1983's Videodrome and rely solely on their television set to keep them company run the risk of encountering something as dangerous as the Videodrome program are liable to experience hallucinations and have massive, wildly-growing tumors in their heads; and surely the characterization of Seth Brundle in 1986's The Fly as a loner who meddles with mysterious new technology and makes the fatal mistake of teleporting himself while a fly is stuck in his telepod while he is desperate and lonely speaks quite strongly of Cronenberg's convictions regarding the dangers of social isolation. And while Scanners may press more heavily on this issue than most of his other films, the fact that it is continually weaved throughout many (if not all) of his works is a testament to just how fascinated, and possibly genuinely concerned Cronenberg seems to be with the motif of social isolation and its accompanying treachery and perilousness.
