Empire consists of one stationary shot of the Empire State Building taken from the forty-fourth floor of the Time-Life Building. Jonas Mekas served as cameraman. The shot was filmed from 8:06 p.m. to 2:42 a.m. on July 25-26, 1964. Empire consists of a number of one-hundred-foot rolls of film, each separated from the next by a flash of light. Each segment of film constitutes a piece of time. Warhol's clear delineation of the individual segments of film can be likened to the serial repetition of images in his silkscreen paintings, which also acknowledge their process and materials.
Warhol conceived a new relationship of the viewer to film in Empire and other early works, which are silent, explore perception, and establish a new sense of cinematic time. With their disengagement, lack of editing, and lengthy nonevents, these films were intended to be part of a larger environment. They also parody the goals of his avant-garde contemporaries who sought to convey the human psyche through film or used the medium as metaphor.
