Consider the premise of Dark City. A species of “Strangers” who inhabit the bodies of dead humans have created a massive laboratory somewhere in outer space to perform experiments in search of that x factor the human soul. The lab itself resembles a weird amalgam of different periods and styles, though it is most notably an extreme version of Noir. Every midnight– a meaningless distinction because there is no sun and thus the city-laboratory inhabits a permanent midnight– the Strangers busily produce a plethora of objects– personal effects, papers, keepsakes, etc.– intended to support the new memories implanted in experimental subjects such as John Murdoch. They revise the city by “Tuning”– essentially harmonizing their psychic power, which is then amplified by some unspecified machinery. As if in a fairy tale, each night spirits fiddle with the world while mortals sleep, unaware.
