In the 80s, as in no other decade before, filmmakers tackled the very foundation of film aesthetics: the physical and psychic constraints of seeing. They set themselves the task of making sight itself visible. The renaissance of science fiction movies, for example, was largely due to new developments in technology that made it possible to create even more perfect illusions. The 80s were a decade for adventurers some of them visionaries, and some, perhaps, vainglorious. But what all these films have in common is their desire to restore mystery to the world.
