The 1980s were a seminal decade for sci-fi. We had bold visions of what technology could become as humanity’s future flourished on the big screens. After George Lucas proved that the genre could deliver at the box office, every studio began chasing the next Star Wars. Which led to the arrival of mega-budget spectacles like Alien, Blade Runner, and The Terminator; all these movies transformed sci-fi into a spectacle.
