Summer is only just kicking off, but there's plenty of viewers who already can't wait for the fall, if only for the third season of The Walking Dead to premiere on AMC. Thankfully, though there's months until we see the premiere, AMC is teasing viewers with a behind-the-scenes featurette of the first episode of the third season, already in production. Words like dark, ominous, harder, faster are all tossed around by cast members like Andrew Lincoln and Norman Reedus. There's also hints and mentions of new characters we've already heard about including David Morrissey as The Governor and Danai Gurira as Michionne . There will be a great link behind the camera from the second season finale to the third season premiere as Ernest R. Dickerson is at the helm of both. Anyway, I'll let the featurette talk about the rest after the jump.Featurette via AMC.
