The Viennese artist, Virgil Widrich, released this short film in 2001 to critical acclaim and the process for which it was made is incredible. The story tells the tale of a man who works in a copy shop who goes on to copy himself until he fills the world.
First filmed on mini-DV, the entire film was then printed frame-by-frame (18,000 frames) and each frame was photocopied. Then each photocopy was re-shot to 35mm to create the final film.
There's lots of good stuff at the official site HERE covering the theory behind the film, the making of, and a nice bit on "copy art". A DVD featuring four of Wildrich's innovative shorts including "Copy Shop" is available HERE.
