Director Ridley Scott and actor Harrison Ford had disagreements about the script almost from the very start. Ford hated the voiceover which Scott was proposing and he was against the idea that Deckard may be a replicant, feeling it undercut the human story of Deckard discovering his lost humanity (Rutger Hauer agreed completely with Ford on this point). According to Ford, Ridley Scott and he agreed prior to shooting that Deckard was not a replicant, but then Scott went and shot it to imply he could be, which disappointed both Ford and Hauer.
