This film is the greatest casting job ever in the history of Hollywood. Jane Feinberg, Mike Fenton and Marci Liroff (uncredited) did something absolutely magical with Blade Runner. They got some of the greatest B movie actors of all time, including Rutger Hauer, Sean Young, Brion James and, yes, Harrison Ford himself ( like Brad Pitt, Ford is a B movie actor who made it to the A list), all known for their wooden, robotic performances, for a movie about robots who want to be human. It's casting as high art and it's the only movie I can think that works entirely because of its casting.
P.S. Deckert is totally a replicant or the unicorn origami (reminding Deckert of his recurring visions throughout the movie) at the end is pointless.
