The dark horse of this list, A Scanner Darkly is a brilliantly offbeat rendition of the Philip K. Dick novel of the same name. Using animated live action this paranoid picture set in a totalitarian world of the near future sees undercover agent Bob Arctor, played brilliantly by Keanu, trying to hunt down the distributors of a dangerous drug called Substance D. The animation which made this film so unique took 18 months to complete, compared to the 23 days of actual filming.
