'The Walking Dead' featurette promises Season 4 will be 'something huge'

Though only "The Walking Dead" Season 4 premiere episode, "30 Days Without An Accident," has debuted, it's already clear that the show is trying out some new things in this story arc. A new featurette that shows off the behind-the-scenes elements of the show describes some of the ways Season 4 will be different than what's come before.

One of the big changes was the way the Prison is portrayed. Executive producer David Alpert notes that it's not as barren as the location was in Season 3, and it's shown that the lighting changed in the Prison this season.

"They've built a functioning community, which is the first time we've had that in the show," Andrew Lincoln says, in character as Rick. "It is a different feel. Everything's deconstructed, so it feels very grounded, very grungy, very much the show."

Some other teasers were that walker kills from the comics will be incorporated in Season 4, and that the quality of zombie kills will be upped this year. For instance, a car is shown driving over a pile of walkers in one shot, seemingly to ensure they won't be reanimating any time soon.

"Season 4 is kind of a gamechanger. Everything always changes on this show. Nothing stays the same for very long; it's that kind of world," co-executive producer Denise Huth teases. Gale Anne Hurd says this will be "the best season yet because we're facing threats from so many different aspects."

"The Walking Dead" airs Sundays on AMC at 9 p.m. ET.
