Executive producer Greg Nicotero takes us through "zombie school" in a behind-the-scenes featurette for Season 4 of The Walking Dead, which began production today in Atlanta. This video shows some of the training that extras have to undergo, in order to perfect their own distinct zombie walk. We also hear from a few of the extras who will likely be featured as zombies in the Season 4 Premiere, debuting this October on AMC.
