interesting bit on /. about bladerunner biz and deckard being a replicant according to ridley scott. of course, it should be noted that the numbering difference that the bbc author cites is really a continuity error. jabber posts his argument supporting the deckard as replicant theory.
for me, there really isn’t that much controversey in the director’s cut because of the unicorn dream/origami.
others on /. have pointed out that future noir reveals a disagreement between scott and the screenwriter(s?) about deckard’s nature (afaik also, deckard was not a replicant in dadoes). obviously the director’s cut reflects ridley scott’s opinion, while the original leaves it much more ambiguous (also w/ the tacked on studio ending though…).
