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 Night of the Living Dead (1968).
Begins on the same day as Night of the Living Dead (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).
Shot over a period of only 23 days.
Even before Land of the Dead (2005) was released, George A. Romero was planning a found footage take on the zombie apocalypse.
