For Season 4 of The Walking Dead, Norman Reedus, who plays Daryl Dixon, recently teased, "They've introduced a way to make zombies scary again, and they're terrifying. The new threat is just unreal. I can't of course tell you what that is, but it's brilliant writing." Now, AMC has provided us with our first look at exactly what Norman Reedus was talking about. The photo above is the very first official photo of a Season 4 walker. There does seem to be a somewhat scarier, thinner look to the walker. We wonder if these new walkers might be a little faster than the older walkers as well. AMC will be releasing the first trailer for The Walking Dead Season 4 on Friday, July 19th, so we should get our first look at these new walkers in action soon. The Walking Dead Season 4 will air on AMC starting in October.
