Long before computer-generated imagery took over, creative thinkers were finding ways to tell compellingsci-fi stories in the 1950s, 60s, and 70s with limited budgets and big ideas. Sci-fi allows us to imagine things that might one day be possible, offering glimpses of the future to tell us something about the present.
