I love collecting old SciFi and hadn't heard of "World on a Wire", so am grabbing a copy now (Criterion have a version). I've long been a fan of Colossus as it raises the spectre of being under constant observation (now almost commonplace it seems).
I miss the days when SciFi didn't mean an action film in a future setting that just ends up being the good guy(s) being chased by the bad guy(s).
Edit: Apparently I had heard of World on a Wire, but forgot about it as I've already got a copy as a series rather than a film.
I find that one over-long and sometimes shoddily done. The payoff at the end is nice though. Fassbinder, the director, was obsessed with his work and made a lot of "legendary" films, but never really made them up to the highest standards.
"The 13th Floor" is another version of that story.
If you enjoy this age of SciFi and don't mind radio drama rather than film, then X-1 is well worth checking out. It's a 1955- radio drama with a different short story each episode, quite a few stories from well recognised authors.
