World Zombie Day is an international annual event that grew from Pittsburgh’s first Zombie Walk at Monroeville Mall in 2006 – the site where George Romero filmed Dawn of the Dead – to help all fans of Zombie culture come together in an international effort to relieve hunger and homelessness. More than 50 cities worldwide participate in World Zombie Day, including New York, Pittsburgh, Paris, Hong Kong, Los Angeles, Chicago, Dallas, Seattle, and Tokyo.
