Andy Warhol's Empire (1964) is an eight hour motionless shot of New York's Empire State Building, filmed by Jonas Mekas from the 41st floor of the Time-Life building. Perhaps the scratches and smudges on the film's emulsion lend some visual variety, but what is really interesting about the film is its strange connection to all the videos taken of the twin towers of the World Trade Center on the morning of September 11, 2001. Home video and news footage on that morning held long static shots of the tops of the skyscrapers before they fell; seeing Empire is a reminder of those 9/11 images.
