The Walking Dead invade London!

 World Zombie Day is an international annual event that grew from Pittsburgh’s first ever Zombie Walk at Monroeville Mall in 2006 — the setting for Dawn of the Dead. Now, more than 50 cities participate in the event. Thousands of people around the world donned zombie costumes Saturday to mark World Zombie Day, a fundraiser to combat hunger that was filled with fake blood and brains. Participants asked to donate non-perishable food for local food banks before the event.
