The world of "Hard to Be a God," a sci-fi film decades in the making and only completed after the death of its visionary Russian director Aleksei German, is inescapably fetid and squalid. Everybody spits—and almost constantly. They spit straight down on the ground when they're walking outside, or even when they're inside. They spit when they smell something foul, which is often. The ground is a filthy, muddy bog in either location. Stagnant puddles are just as likely to contain urine and feces as water from the steady rain showers. Various bodies—chicken, geese, dogs, foxes, swine, and no shortage of humans—hang from spits and walls and ceilings, in various states of decay. And while bites or sips of things are sometimes savored, they're just as frequently expectorated onto the floor, into the air, or into the face of whomever is nearby. And they often follow the spitting by blowing snot across the room too.
