Blade Runner, from 2019 to 2049. Science fiction cinema as disseminator of Science

Abstract

Thirty-five years have passed from Blade Runner (Scott, 1982) to its sequel (Blade Runner 2049, Villeneuve, 2017) and this gives us the opportunity to see to what extent changes in our culture have modified the discourse of one of the best science fiction films that with greater emphasis represented the fear of the adverse effects of progress. From a sociological perspective, the comparative analysis carried out between the two films shows that the apocalyptic alarmism, characteristic of the genre during most of the past century, has given place to a more lucid and complete vision of the risks, possibilities and dilemmas that awakens the techno-scientific advance and establishes the science-fiction genre as a valuable resource for its reflection and dissemination.
