Filming locations can be integral to a movie or TV show’s success. A certain stairway, a library, a house can take on a life of its own by uniquely framing a movie or setting the stage for a memorable scene. One such location that is near and dear to the hearts of horror fans may be in jeopardy.

The Monroeville Mall in Monroeville, PA, which was the setting for George A. Romero’s Dawn of the Dead, has been sold to Walmart. The company hasn’t disclosed if they will keep the mall or knock it down to build a new store. The retail chain does not currently have a location in Monroeville.

Dawn of the Dead was released in 1978, ten years after Romero had made his groundbreaking zombie film, Night of the Living Dead. The long-awaited sequel is set at a time when zombies have overrun the US and nowhere is safe. It follows a group of people, including a TV reporter, a producer, and two SWAT team members, who take refuge in a mall.

Since the iconic zombie movie was released, the Monroeville Mall has become a popular tourist destination for horror fans. It has hosted zombie walks, tours, and conventions, it is home to The Living Dead Museum, and contains a bronze bust of Romero.

Ken Foree, who starred in the movie as SWAT officer Peter Washington, is among those leading the charge to save the mall. On Facebook, he wrote about the mall’s history and its significance, questioning if it could attain historical landmark status and be protected from destruction.

“Its fans have cherished and preserved this film to hand down from grandfather to son, son to grandson; a rite of passage. This small low budget film led Variety in gross sales for almost three weeks; unheard of! It impacted a generation,” Foree wrote. “DOTD was so popular that fans from all over visit ‘The Mall’ just to be where it all happened. For decades the owners of ‘The Mall’ have graciously permitted zombie walks, conventions, and tours of its celebrated halls. George Romero’s films and the cadre of local Pittsburgh extras and actors are celebrated there. No one who participated in a George Romero film can deny that they owe allegiance to ‘The Mall.’ ‘Build it and they will come:’ Well, they have from every country to pay homage. Perhaps a place should be preserved for George’s bust and the Living Dead Weekend Museum.

A petition to preserve the Monroeville Mall is currently accepting signatures and support on change.org.
