zombie films in the early 2000s, including films featuring fast-running zombies—such as 28 Days Later (2002), the Resident Evil and House of the Dead films, the 2004 Dawn of the Dead remake, and the British zombie comedy Shaun of the Dead (2004). The "zombie apocalypse" concept, in which the civilized world is brought low by a global zombie infestation, has since become a staple of modern popular art, seen in such media as The Walking Dead franchise. The late 2000s and 2010s saw the humanization and romanticization of the zombie archetype, with the zombies increasingly portrayed as friends and love interests for humans. Notable examples of the latter include movies Warm Bodies and Zombies, novels American Gods by Neil Gaiman, Generation Dead by Daniel Waters, and Bone Song by John Meaney, animated movie Corpse Bride, TV series Pushing Daisies and iZombie, and manga/novel/anime series Sankarea: Undying Love and Is This a Zombie? In this context, zombies are often seen as stand-ins for discriminated groups struggling for equality, and the human–zombie romantic relationship is interpreted as a metaphor for sexual liberation and taboo breaking (given that zombies are subject to wild desires and free from social conventions).

The Oxford English Dictionary gives the origin of the word as Central African and compares it to the Kongo words "nzambi" (god) and "zumbi" (fetish). In Haitian folklore, a zombie (Haitian French: , ) is an animated corpse raised by magical means, such as witchcraft. The concept has been popularly associated with the religion of voodoo, but it plays no part in that faith's formal practices. How the creatures in contemporary zombie films came to be called "zombies" is not fully clear. The film Night of the Living Dead made no spoken reference to its undead antagonists as "zombies", describing them instead as "ghouls" (though ghouls, which derive from Arabic folklore, are demons, not undead). Although George Romero used the term "ghoul" in his original scripts, in later interviews he used the term "zombie". The word "zombie" is used exclusively by Romero in his script for his sequel Dawn of the Dead (1978), including once in dialog. According to George Romero, film
