Edgar Wright's Shaun of the Dead is basically a hilarious (and hilariously meta) homage to previous horror flicks. Obviously, the movie's title is a play on George Romero's second big zombie flick, Dawn of the Dead. Speaking of which, Shaun yells at Ed for referring to the shuffling undead as the "Z word," which calls back to the fact that the characters in Romero's movies don't call their antagonists zombies. When Shaun tries to book a date for himself and Liz, his phone book features an Italian food place called Fulci's—a reference to Zombie director Lucio Fulci.
Elsewhere in the film, the supermarket clerk that Shaun and Ed throw vinyl records at worked at a grocery called Landis Supermarket, which is a nod to John Landis, the director of Michael Jackson's zombie-filled music video for "Thriller." Shaun's place of employment, Foree Electric, is named after actor Ken Foree, who played one of the main characters in Dawn of the Dead. Ed saying "we're coming to get you, Barbara," calls back to Russell Streiner's iconic line to Judith O'Dea in Night of the Living Dead. In return, Romero cast Wright and Simon Pegg (Shaun) as "Photo Booth Zombies" in Land of the Dead.
