- They're still here. - They're after us. They know we're still in here. - They're after the place. They don't know why, they just remember. Remember that they want to be in here. - What the hell are they? - They're us, that's all, when there's no more room in hell. - What? - Something my granddad used to tell us. You know Macumba? Voodoo. My granddad was a priest in Trinidad. He used to tell us, "When there's no more room in hell, the dead will walk the Earth."
Dawn of the Dead, George A. Romero (1978)
