Blade Runner (1982), directed by Ridley Scott and starring Harrison Ford and Rutger Hauer, is set in a dystopian 2019 Los Angeles where a detective must hunt down four escaped bioengineered humanoids. Hauer's improvised Tears in Rain monologue is one of cinema's most celebrated death scenes.

Why It Matters

• Defined the visual grammar of cyberpunk — neo-noir rain-soaked cityscapes, neon advertising, architectural decay — copied by every science fiction film and game that followed
• Douglas Trumbull's practical effects work on the miniature cityscape has never been surpassed by CGI for sheer tactile beauty
• The Director's Cut and Final Cut removed Harrison Ford's voice-over and the fake happy ending — transforming the film's meaning entirely

The question of whether Deckard is himself a replicant was deliberately left unresolved by Scott and has generated debate for four decades. The film was a box office failure on release and is now one of the most culturally influential films ever made.
