10 Awesome Fan Theories That Improve Already Great Films

9. Deckard Is Gaff's Replicant Replacement - Blade Runner

The Theory: Whenever discussing Blade Runner the conversation always tends to turn to the question of whether Deckard is a replicant. And while you can split hairs over unicorns and different cuts of the film all day, when you start looking at the logistics of Harrison Ford's character being one of the very robots he is employed to hunt down things get very interesting. One strong idea is that Deckard isn't just a replicant, but is a replacement for Gaff, complete with the formers memories. How It Improves The Film: Gaff has always been central to the replicant theories - he is the source of the origami unicorn on which the whole idea rests - with it being suggested he's employed to keep an eye on Deckard, but things can be taken even further. Walking with a limp, the theory implies that Gaff was injured in the line of duty with his job taken up by Deckard. We know from Rachel had memories implanted in her and what better way to create a new Blade Runner than to implant memories of a previous one? It adds a whole over layer to Gaff's memorable lines; suddenly "You've done a man's job" and "It's too bad she won't live! But then again, who does?" feel a lot more significant now.
