I think it may be time to watch that movie again. I watch it about every four years or so. I especially like the concept art for the movie, which was done by Syd Mead: http://sydmead.com/v/12/
Ain't it cool he's still around?
I'll give credit to everyone on the art staff that worked on Blade Runner, but the vision was solidly Syd's, and they did their darnedest to maintain the fidelity of that vision. I'm pretty sure I've bought some SF books purely on Syd's cover art. There's lots of people I am envious of that can draw so much better than I can, but, Syd, well, he's just slick as snot.
