"'The Dead' are sort of deformed and mutated or a specific set of characteristics. There are seven of them, and they match the seven parts of the viral life-cycle. Each one fulfills a specific sort of mission, and that’s why they have these kinds of ritual poses, which are based on the torments of the damned from Greek mythology. They’re drawn out of a classical idea of a cycle of perpetual punishment."
