6. ‘Night of the Living Dead’ (1968)
Memorable quote: “They’re coming to get you, Barbara! They’re coming for you! Look, there’s one of them now!”
Scare factor: Not only did George Romero’s movie essentially spawn a whole genre with this zombie classic, it also set the standard for the barricade-yourself-in-the-house survival tactic. Admit it: You have assessed your dwelling’s defensive strengths and weaknesses because of this film.
