Nightfall (1971)

Shot in his garage-studio, the camera records Ader painstakingly hoisting a large brick over his shoulder. His figure is harshly lit by two tangles of light bulbs. He drops the brick, crushing one strand of lights. He again lifts the brick, allowing tension to accrue. The climax inevitable—the brick falls and crushes the second set of lights. Here the film abruptly ends, all illumination extinguished.
