The most alarming thing for most of Alien‘s runtime is its stillness. Whether in the claustrophobic, geometrically-shaped industrial corridors of the supermassive space trawler Nostromo, or the fossilized, vaginal caverns of the derelict, Ridley Scott opts for glacial tracks and pans. He wants you to pay attention to every detail, every line in the intricately constructed sets. The environments–the two gargantuan vessels, the planetoid, space itself–aren’t dressing, they loom over everything. Even when events spiral into a delirious mad dash to escape, bathed in primary color lights and steam, Scott keeps us steadily gazing. These are inherently frightening places, unfit for human beings. The crew, particularly Sigourney Weaver’s no-nonsense survivor Ripley, gradually come to understand this. Not only is one of their crew infected, birthing a monster that stalks them, but they’ve been railroaded into their predicament by duplicitous A.I. and a robotic snitch, acting at the behest of amorphous corporate masters.
In that regard, the alien is the perfect metaphor for the exploitation at play here: a drooling, insectoid rapist with a metallic body, perfectly camouflaged to the mechanized hellhole its prey is trapped in. It’s also patient, observing the panicked humans before striking from the darkness to either brutalize, violate, and/or abscond with them. The way the Nostromo becomes slick with humidity, and the crew in a near-constant state of perspiration–harking back to the moment John Hurt’s ill-fated Kane comments on the derelict being tropical–there’s also an implication (outside of the famously deleted “cocoon” scene) the creature is fashioning a new home for itself. Like the company, it views the humans already occupying these spaces as property to lay claim to. Grist for its own expansion, or brood mothers fit only to birth future offspring. The methodology might be uncanny and gruesome, but the more we gaze, the more eerily familiar the alien’s behavior becomes.
