When it comes to science fiction cinema, it’s generally thought that the 1970s or 1980s were the decades in which the genre really took off, so to speak. We may be partial to the '70s, with its Star Wars and its Alien. Or we may fawn over the '80s with films like Blade Runner, The Terminator, and so much more. But both of these decades owe something to the more modest, unassuming sci-fi of the ‘60s.
