All the extras who portrayed zombies in the climax received for their services a cap that said "I Played A Zombie In 'Day of the Dead'", a copy of the newspaper from the beginning of the film (the one that says THE DEAD WALK!), and one dollar.
Some of the headlines from the newspaper that says "The Dead Walk": "Vice President Declares State of Emergency," "Whereabouts of President Unknown," "Food Supply Dwindles" and "Man Bites Man."
On the special edition DVD, director George A. Romero claims this is his favorite film out of the original "dead trilogy".
The original script, for which George A. Romero couldn't get budget, involved the scientists living above ground in a fortress protected by electrified fences and the military living safely underground. It also involved a small army of trained zombies, and the conclusion to the trilogy more brutal than the released version. This later became the basis of Land of the Dead (2005)
The lowest grossing film in George A. Romero's "Dead" trilogy. Nonetheless, it's gained a cult following over the last three decades.
