In the warehouse, when the group is searching the RV for the missing dead body, you can hear a television report in the background. The report is taken directly from George A. Romero's Die Nacht der lebenden Toten (1968).
Begins on the same day as Die Nacht der lebenden Toten (1968), although the setting has been updated to the present day. The concept for the film evolved from an idea that George A. Romero had earlier for a "Living Dead" television series, which also would have begun on the same day as Night of the Living Dead (1968).
Even before Land of the Dead (2005) was released, George A. Romero was planning a found footage take on the zombie apocalypse.
The documentary-within-the-film is called "The Death of Death." This is also the name of George Romero's four-part miniseries for the DC Comics zombie title "Toe Tags."
