Blade Runner cityscape concept by Syd Mead. Could be the only one painting from preproduction that shows cityscape during the day. However the concept is never used for various reasons. One of them is: not enough money to develop day scenes that will actually work and follow the distopyan concept of the movie.
“Mark Stetson sets up a miniature cityscape on an EEG soundstage. The buildings shown here represent the variety of techniques and resources used on the project. For example, one of the original, large-scale miniatures built for the film is the left foreground, while Stetson is working on a row of miniatures greatly-deminished scale, originally built for ESCAPE FROM NEW YORK. The view beyond Stetson, showing buildings hundreds of stories tall, is rear-projected Syd Mead painting. The film’s cityscapes were a hodge-podge of variously-scaled structures, rearranged for each particular shot.”
