Blade Runner, you see, represents perhaps the high water mark of the now seemingly lost art of miniature-based practical visual effects. Most everything in its slickly futuristic yet worn and often makeshift Los Angeles actually existed in reality, because, in that time before realistic CGI, everything had to take the form of a model (or, farther in the background, a matte painting) to get into the shot at all. You can take an extensive behind-the-scenes look at the blood, sweat, and tears involved in building all this in a gallery showcasing 142 photos taken in the Blade Runner model shop.
Partisans of these sorts of techniques argue that miniatures remain superior to digital constructions because of their perceptible physicality, and perhaps that very quality has helped keep the look and feel of Blade Runner relatively timeless. Plus, unlike CGI, it gives die-hard fans something to hope for. If you dream about owning a piece of the film for your very own, you theoretically can; just make sure to do your homework first by reading the threads at propsummit.com, a forum about — and only about — Blade Runner props.
