The Quick and the Undead(2006)
The movie takes place in the present, but in this universe, a plague has broken out and the infected have been transformed into zombies. No explanation is provided for the source of the plague, nor is it explained how the original victims were infected, since by the time the narrative begins the infection spreads by bite. Nevertheless, the action starts 80 years after the initial outbreak. The western United States has devolved into a disconnected series of ghost towns overrun by zombies, and the government is awarding bounties in exchange for the pinkies of the undead.
