Runaway is a 1984 American science fiction action film written and directed by Michael Crichton, starring Tom Selleck, Gene Simmons, Cynthia Rhodes and Kirstie Alley. Selleck portrays a police officer assigned to track down dangerous robots, while Simmons is a scientist who hopes to profit from his manipulation of robots. The film was a box office disappointment and received mixed reviews.
If I remember right that's actually the bad guy's gun and it fires bullets that chase you! (At approximately the speed a human can run). Its silly and great and if I was remaking it for a modern setting, it'd be some kind of launcher/targeter for tiny suicide drones.
I just watched it, and it was pretty cliche-ridden. But it's worth remembering that it came out in 1984, and a lot of tech in it that seems standard now, didn't actually exist (at least as consumer electronics) at that time:
tablet-like portable computers
earbud cellphones / walkie-talkies?
door camera recordings
retinal biometrics
text-to-speech
voice user interfaces to databases
mobile phones
This was written by Michael Crichton, after Congo and before Sphere, and about 9 years before Jurassic Park. I don't know if I'd classify it as cyberpunk primarily; more like a techno-thriller, which is the sort of thing Crichton was known for.
Besides the obvious stars, the music was composed by Jerry Goldsmith:
He composed scores for five films in the Star Trek franchise and three in the Rambo franchise, as well as for films including Logan's Run, Planet of the Apes, Tora! Tora! Tora!, Patton, Papillon, Chinatown, The Omen, Alien, Poltergeist, The Secret of NIMH, Medicine Man, Gremlins, Hoosiers, Total Recall, Basic Instinct, Air Force One, L.A. Confidential, Mulan, and The Mummy.
According to the movie end titles, the music was "performed on Yamaha Digital Instruments". At the time was still fairly novel, and this is the type of sound that would go on to inspire various modern electronic music movements, such as synthwave.
