December 13, 2013 Grantville - AMC show The Walking Dead was filmed entirely in Grantville. New business opened after the show filmed in downtown Grantville on Friday, December 13, 2013. Movie production in Georgia is big business not only for production crews and Georgia-based actors: towns increasingly will do whatever is asked of them for their 15 minutes of fame and, hopefully, long-term economic benefit. Jim Sells, major of Grantville, ignored his city council and painted the freight depot to attract an episode of � Walking Dead.�rantville now attracts visitors from around the world. Nearby Senoia also bends over backwards for the zombie movie makers. Covington is famous for the Vampire Diaries (and The Heat of the Night). HYOSUB SHIN / HSHIN@AJC.COM
