In 1968 a young college drop-out named George A. Romero directed “Night of the Living Dead,” a low-budget horror film that became a kitschy cult classic and launched a zombie craze that’s now a full-blown, zillion-dollar industry. The new film “The Birth of the Living Dead,” screening Monday, January 5 at the Sebastiani, documents how Romero pulled off the unlikely success, introducing the flesh-eating undead into the canon of horrific movie icons. 7 p.m. $8. 476 First St. E. 996.2020.
