Watch 21-87 (1963) Official Trailer

This short film from Arthur Lipsett is an abstract collage of snippets from discarded footage found by Lipsett in the editing room of the National Film Board (where he worked as an animator), combined with his own black and white 16mm footage shot on the streets of Montreal and New York City, among other locations. A commentary on a machine-dominated society, it is often cited as an influence on George Lucas's Star Wars and his conceptualization of "The Force."
