The word “zombie” is never used in director George A. Romero’s groundbreaking 1968 horror film Night of the Living Dead, yet the movie effectively invented the reanimated horror trope. Night of the Living Dead became a worldwide sensation, and Romero’s sequels, 1978’s Dawn of the Dead and 1985’s Day of the Dead, used the horror genre to offer biting social commentary amid the gore. All three films screen at the upcoming CULT Film Series tribute to the director, who passed away in July at the age of 77. Revisit the greatest hits from the godfather of the dead on Thursday, Sept. 7, at Roxy Stadium 14 Cinemas, 85 Santa Rosa Ave., Santa Rosa. 7pm. $10. 707.525.8909.
