The Walking Dead takes place in a zombie apocalypse, which is not fertile ground for levity. The show is full of fear, doom, and general unhappiness. That doesn't mean it isn't a good time for the audience, as perverse as that may sound. But it's just a TV show, made by real people in a small town in Georgia. When the cameras aren't rolling, zombies and zombie-killers alike drop the apocalypse and turn into regular folks at work. To see them smiling and having fun, still in costume and makeup, is downright weird. See a collection of behind-the-scenes photos of The Walking Dead cast, zombies and all, at TVOM.
