Blade Runner: the mother of all cyberpunk, dark future and product placement movies.  One of those classics which, even if you never watch it, you ought to have at least standing on your dvd shelf ;-).  Anyway, there's a "Special Edition" in the works.  Not to be confused with the 1992 Director's Cut, the Special Edition will feature a better transfer, better sound, and (more) changes by Ridley Scott.  BRMovie.com tells us that the project is currently on hold.
