did any of you catch the two hour show on zombies on cable? i think it was discovery or history. they attribute the popularity of zombies to the cold war and night of the living dead. they also point out that what we call a zombie in pop culture is not the original zombie. they said the zombie originated in voodoo. the program also covered the history of our obsession with the dead rising and the origin of things like crypts and coffins, presumably so they could not rise.
