In this film you can see the source of ideas that continue to echo in the sci-fi genre. Look for source material that led to: the green text computer code of "The Matrix", the android C3PO, the empty white netherworld of "The Matrix", and the first use of the word "wookie". There are many others. The film moves slowly but delivers an enveloping view of a possible future of techno-enhanced fascism. Check out the interview with the sound engineer on the DVD extras.
