Re: Bladerunner - Decker a Replicant???
Check out the anniversary 4 disc collection. It has some outstanding interviews with Ridley Scott and the rest of the cast. Scott pretty much spells it out in the final director's cut that Deckard is a replicant. However, Ford states in his interview that he feels the character works better if he is human. Personally, I like the idea of there being some ambiguity about the issue. Let the viewer decide.
One of the things that makes this one of the best SciFi movies ever is that it's a drama set in the future. Blade Runner asks some very important questions about who and what we are, as well as what defines us. It's not lost it's relevance either, especially with the rapid advancements that are being made in bio-engineering and artificial intelligence. It's also a great movie because it looks so fucking good! Every time I watch it I see something new. It's no wonder that it's listed as #35 on AMC's all time 100 best movies.
