If you've got a zombie itch that you just can't wait till October to scratch, you may want to check out AMC's Walking Dead Season 3 Preview Weekend, ambling your way July 7-8. It will have a marathon of content, as you might expect, including these fun treats: the original pilot episod in black and white, every episode of the first two seasons of the show, and interviews with cast members. After all that, there will be a special edition of Talking Dead, hosted by Chris Hardwick, that will give an advance look at the third season. That all should whet your appetite for zombie destruction for a while.
