The movie was shot on 35mm film by cinematographer Jordan Cronenweth—which means it, you know, predates the digital revolution. Blade Runner has that classic pre-CGI look to it, and the futuristic L.A. sets were actually made by hand. A real camera was swooping over them, gathering in the sights—like when we see the industrial hell-fire torches light up with Tyrell's ziggurat looming nearby.
