An unorthodox work in every way, Godfrey Reggio's Koyaanisqatsi was nevertheless a sensation when it was released in 1983. The film wordlessly surveys the rapidly changing environments of the northern hemisphere. The director, cinematographer Ron Fricke, and composer Philip Glass created an astonishing collage; the film shuttles the viewer from one jaw-dropping vision to the next, moving from images of untouched nature to others depicting human beings' increasing reliance on technology. Often using hypnotic time-lapse photography, Koyaanisqatsi looks at our world from an angle unlike any other.
