Zombie
Hear me out… Admittedly, there have not been too many films in the genre pioneered by George A. Romero that are inspired by true events, considering how those films are, typically, a depiction of the end of days, which has yet to happen. It should be understood, however, that Romero’s definition of “zombie,” referring to flesh-eating corpses, is not the original definition of the word which, indeed, does have an intriguing fact-based history.
