When a disease turns all of humanity into the living dead, the last man on earth becomes a reluctant vampire hunter.
By night they leave their graves, crawling, shambling, through empty streets, whimpering, pleading, begging for his blood!
The Shining, The Exorcist and The Omen are all films that owe some of their stylistic approach to this film. This is the film that re-wrote the rules of the horror genre as it went along, whilst acting as both social critique and fond homage to 'The Birds' as well.
Romero set in place a steady breakdown of all our assumptions of the horror film, which he then utilised to full effect through the rest of this film and the two superb sequels that followed.
