night of the living dead (1968)

aka Night of the Living Dead: 30th Anniversary Edition. Laugh Track: Night of the Living Dead, Monster Flick. Night of Anubis. Night of the Flesh Eaters.
The dead become re-animated and determined to feed on the living. Anyone bitten by a zombie then returns as a zombie themselves. The only way to destroy them is to destroy their brain. A number of people try to escape the chaos and end up barricaded inside a remote farmhouse, besieged by an increasing zombie hoard. As the zombies attack the tensions inside the house increase.
The realistic almost documentary feel and downbeat conclusion adds to the films tension and helped usher in a new era of contemporary horror. A wonderfully realised low budget film, that set the standard for what was to come.
