I lived it for real
In my student days, not long after the release of Alien, I had a summer job doing night-shift security work in a Silvertown paint factory. Man, it was like the spitting image of the Nostromo interior in that place. Dark, pipes everywhere, blinking lights, claustrophobic corridors, cavernous rooms full of oily machinery, strange noises, an oddball technician doing experiments in a lab somewhere. On my hourly patrols, the Alien was on my mind most of the time. My nerves weren’t helped when, very occasionally, one of the few night workers would randomly appear out of nowhere. That job really scared me.
