November 22. An Evening with Gregory Waller. Zombie stories are everywhere, in movies and TV. Dr. Gregory Waller, a professor at Indiana University, will theorize why, and also show clips from a rich history of zombie movies, some made long before Twilight and The Walking Dead. Professor Waller is the author of American Horrors: Essays on the Modern American Horror Film and the classic work, The Living and the Undead: From Stoker’s Dracula to Romero’s Dawn of the Dead.
