George Andrew Romero Jr. was an American-Canadian film director, writer, editor and actor. His Night of the Living Dead series of films about a zombie apocalypse began with the original Night of the Living Dead (1968) and is considered a major contributor to the image of the zombie in modern culture. Other films in the series include Dawn of the Dead (1978) and Day of the Dead (1985).

Zombie apocalypse is a subgenre of apocalyptic and post-apocalyptic fiction in which society collapses due to overwhelming swarms of zombies. Typically only a few individuals or small bands of survivors are left living. In some versions, the reason the dead rise and attack humans is unknown, in others, a parasite or infection is the cause, framing events much like a plague. Some stories have every corpse rise, regardless of the cause of death, whereas others require exposure to the infection.
