“The Walking Dead” has currently filmed up through its fourth episode of Season 4, and the AMC comic book adaptation is slated to have a big presence at San Diego Comic-Con in 2013. With the fourth season so far into production, it seems safe to assume that those involved in the series would be willing to spill the beans on what’s in store when “The Walking Dead” returns later this year.

Not producer David Alpert, though. He played coy when asked about some key plot points that are yet to be revealed about the upcoming season — like, say, where the Governor is and when we’ll see him again.

“I don’t know. I don’t know. Is he in the show? Is he not in the show? Who knows?” Alpert tells Zap2it on the 2013 Saturn Awards red carpet. For the record, David Morrissey is returning

Alpert continues of the Governor, “What happened at the end of Season 3? He went kind of crazy, don’t you think? So he might have an army, or he might be living out alone in the woods. We don’t know. You’ll have to wait until October to find out. “

It was a bit surprising that “The Walking Dead” ended its third season with Rick and his group of survivors remaining at the Prison and integrating those left alive at Woodbury into their home. Alpert promises that the Prison won’t be the only location that Season 4 takes place in, though.

“There is going to be some new settings this year. There’s no doubt about that. No doubt,” Alpert answers.

So just how far away from the Prison and Woodbury are we talking? “I don’t know the exact distance because one, we haven’t written all the episodes, and two, I’m very bad at directions,” he says. “That said, we’re going to go pretty far out from the prison. But we’re also going to be in the Prison too. There’s going to be some pretty interesting stuff that goes on. We’re going to go back and forth.”

Expect the tone of “The Walking Dead” to get even more intense with new showrunner Scott Gimple on board in Season 4.

“I think it’s going to be bigger, better, meaner. I think we saw the evolution of the threat,” Alpert teases. “I think sort of as society begins to come back together and disintegrate at the same time, there’s going to be more of [the threat of man]. … We’re going to explore those themes in ways that have yet to be explored. We’re going to get a whole new direction coming up in Season 4.”

“The Walking Dead” will have a panel at San Diego Comic-Con. The fourth season premieres in October on AMC. Watch the above video to find out what sort of presence “The Walking Dead” will have at Comic-Con.
