AMC's hit show is still going strong, as evidenced by the packed Hall H for "The Walking Dead" panel at Comic-Con International in San Diego.

The crowd was graced with a massive group of panelists, composed of actors Andrew Lincoln, Norman Reedus, Steven Yeun, Lauren Cohan, Danai Gurira, David Morrissey, Scott Wilson and Chad Coleman and executive producer and showrunner Scott Gimple, executive producer and co-creator Robert Kirkman, executive producer Gale Anne Hurd, executive producer Dave Alpert, and special effects makeup supervisor and executive producer Greg Nicotero.

Of the show's upcoming fourth season -- which premieres Sunday, October 19 -- Kirkman said, "Things are definitely gonna be way crazier! It's gonna keep progressing, if you can believe it." Gimple added, "It's going to get insane very quickly." Furthering the tease, Nicotero exclaimed, "There's stuff that we shot in the last two weeks that's above and beyond...24 hours ago, we shot one of the coolest walker gags ever."

And what will become of The Governor this season? "He received some negative reinforcement, and it's going to affect the character," said Gimple. "All bets are off," Kirkman added. "He's still out there, but how and when he returns is going to be a huge issue this season."

Without further ado, the lights dimmed and fans were treated to a world premiere fourth season trailer that illustrated the powder keg of a scenario brewing amongst the show's players.

As the cheering crowd reacted, the cast was called onto stage to roaring applause. Getting right into it, Lincoln was asked why the group would go back to the prison. "I'm not sure I can answer it, because we answer it in this season," he teased.

He went on to call his relationship with Carl "integral" to season four, explaining that Rick is, "In a completely new place at the beginning of this season...he's trying to repress his brutality and he's renounced positions in leadership for the sake of his children."

Reedus also chimed in about how his character begins the season, in the wake of losing Merle. "He was sort of doomed to become mini Merle," he said. "Without Merle around, he can find this sense of self worth that he never would've found if this apocalypse had never happened. These people are this family that he never had before...he's definitely grown up a ton. Nobody's the same as they were in the first season."

Audience members had romance on their minds -- a Michonne/Rick pairing was proposed, to which Kirkman said, "Anything is possible."

Reedus piggybacked off the idea, explaining that -- because of the shared pain of losing someone -- Michonne and Daryl might make a nice pair. "Everyone's losing people left and right, but both those characters are sort of loner characters who are learning to deal with a group and be part of a group, and I think it'll just bring us closer together." He went on to joke, "Maybe we'll get together. And Rick can join!"

Season 4 of "The Walking Dead" premieres Sunday, October 19.
