Funny thing about this topic... When I think of techno films, I think of films that I would love to hear rescored by a techno artist. They would be:
The Crow The Killer Hardware The Professional ("Leon" outside of the states) Akira Riding Bean The Matrix A Better Tomorrow Hard Boiled (yes, I love the old John Woo/Chow Yun Fat flicks) Black Moon Rising The Terminator And a few other anime titles that I can't seem to remember the names of.
