The Blade Runner Phenomenon: Ridley Scott's cult film Blade Runner, based on a novel by Philip K. Dick and released in 1982, is one of the most influential science fiction films ever made. Its depiction of Los Angeles in the year 2019 is oppressively prophetic: climate catastrophe, increasing public surveillance, powerful monopolistic corporations, highly evolved artificial intelligence; a fantastic vision of the future world that has become a frightening reality.
