This document summarizes the history and evolution of the zombie genre in cinema. It begins with early influential films from the 1920s-1940s that helped establish tropes of the genre. George Romero is credited with beginning the modern zombie film with Night of the Living Dead in 1968, setting conventions like flesh-eating zombies and survival in an enclosed space. The genre then expanded with Italian zombie films and comedic takes in the 2000s, as well as fictional depictions of "real" zombies.
