8. Blade Runner (1982)
The works of Philip K. Dick have suffered greatly from loose and unfaithful movie adaptations: it's not just
Blade Runner that got a major overhaul on the big screen, but famous movies like
Total Recall and
Minority Report were adapted with little allegiance to their source material. The fact that Blade Runner was granted a title that bears absolutely no resemblance to the book it was based on should probably be a tell-tale sign that there were going to be some differences, but to call Blade Runner an adaptation of "Do Androids Dream of Electric Sheep?" is misguided as hell. This all stems from the fact that both
Blade Runner and "Do Androids Dream of Electric Sheep?" set out to make different points entirely: whereas
Blade Runner is a story about replicants trying or learning to be more like humans, "Androids" is a story about humans gradually becoming more like machines. Whereas the Deckard of the novel is subjected to some serious changes, the Deckard in the book goes through barely any changes at all. Ridley Scott's movie also clings to a film noir-ish structure, which Dick's novel lacks. Much more of an "inspired by" than an adaptation or "based on," here are two great works that tell two very, very, very different stories.
