The fall just got a whole lot darker: The third season premiere of AMC's hit TV series, "The Walking Dead" is just three weeks away. And with the season three opener approaching faster than a walker on a dinner-run, we're hearing more and more rustlings from cast and crew every day now on what to expect from the new season.

Based off the monthly black-and-white comic book series written by Robert Kirkman, "The Walking Dead" follows a gang of lost souls just trying to survive day-to-day life in a zombie-ridden wasteland. The first two seasons of the AMC series have been hugely-successful. After the season two premiere broke cable ratings records in the 18-49 demographic AMC renewed the show for a third season.

But because ammunition continues to get harder and harder to find, Nicotero said Rick and company will have to come up with more creative (read: violent) ways to kill zombies.

"I think one of the things that we discovered in season three is, clearly in the world that we live in, ammunition is valuable. More valuable than anything else," he said. "The walker kills in season three tend to be a lot more hand-to-hand, so you have to get in close proximity to them. So, with that said, there's a lot of crowbars and there's a lot of hammers and there's a lot of crushed heads and smashed-in heads and axes and machetes and stuff like that."
