Dawn of the Dead (1978, It./US)

In George Romero's horror sequel to his Night of the Living Dead (1968):

• the memorable scenes in which marauding, staggering, flesh-eating zombies in a deserted suburban Pittsburgh shopping mall relentlessly engaged in attacks upon the living survivors: pregnant TV anchorwoman Francine (Gaylen Ross), her boyfriend, helicopter pilot/TV news-traffic reporter Stephen (David Emge), and two SWAT cops Roger and Peter (Scott Reiniger and Ken Foree)
• the biting social satire that equated zombies with consumers (as perky, goofy mall music played, zombies stumbled around on escalators, etc.)
• the climactic band of about a few dozen bikers in a motorcycle gang that attacked the mall and the zombies inside, and when outnumbered by the hungry creatures, their eviscerated bloody flesh was fought over

Stephen's Death and Re-Animation as a Zombie

• the chilling zombie attack and death of Stephen: he was first shot in the arm by fleeing bikers; then he was assaulted inside a mall elevator and bitten in the leg and neck by the undead, and began to bleed profusely - hours later when the doors opened, his reanimated zombie corpse joined the army of undead who now had infiltrated into every mall store
