Zombies, within literature and film, are reanimated corpses resurrected by mystical or biochemical means. They have their origins in voodoo folklore, in which voodoo priests would raise the dead to do their bidding. Night Of The Living Dead introduced the concept of zombies attacking and consuming the flesh of the living. In 1985, the film Return Of The Living Dead introduced the concept of zombies consuming the brain matter for their endorphin content to ease the pain of rotting away. Popular zombie movies include Night of the Living Dead, Dawn of the Dead, and, more recently, 28 days later. According to Bob Hope in the movie The Ghost Breakers, they are like Democrats because of their penchant for blind following.
