'The Walking Dead' Season 4 Spoilers: New Rick, New Threat and More Secrets

All is right in the universe. The cast and creators of the AMC series "The Walking Dead" have revealed everything fans need to know before heading into Season 4. There have been rumors of a terrifying new threat, a new prison with splendid décor, of course more intergroup drama, and much more. With new showrunner Scott Gimple taking the reigns, there's sure to be plenty of new twists and turns that will rock the show harder than ever before.

"We're taking the greatest hits approach of all the things I loved that we've done and grabbing from all the different seasons and working it up. There are a lot of characters that are dead on the show that aren't dead in the books. There are a lot of characters on the show that aren't in the book," Gimple said during a chat with The Hollywood Reporter. "You'll also see stories that are totally outside of the comic that have never been seen before. But the basis for those stories are totally from the spirit of the stories told in the comics."

As the community grows with the prison, tensions will boil to an extreme. "The focus really is on characters, the conflicts," said executive producer Gale Anne Hurd. "It's a larger group and it's harder. We're integrating a group that when we ended last season was at war and shooting each other."

"The community is growing and that mixes with the fact that there's less of a dictatorship than there has been," added Steven Yeun, who plays Glenn on the show.

As for Rick (Andrew Lincoln), "he's a man that is wrestling with a motor that didn't work last season," said Andrew Lincoln. "He's trying to suppress the brutality for the sake of both of his children and trying o be a parent in an apocalypse and trying to return to the man he once was."

"He's trying to find a way to add value and help and try to find a place for himself inside the community where he can do that without having to be the alpha male making all the decisions," said executive producer Dave Alpert. "This is a very different Rick. How long that can last, however, is another question."

According to the comics, Rick will lose a hand to The Governor in the upcoming season, a possibility that Alpert said is still in the cards. "It was one of those things where, given all the other things going on [in season 3], we decided it was too much to put on. That's not to say we're not going to do it later, but there's too much of a burden."

And finally, that new, mysterious threat. "It's someone we haven't seen before. Someone unusual. You can't stab them in the face, you can't reason with it," said Gimple. "It's a force that would be dangerous in this world and in the world of 'The Walking Dead,' it's terrifying."

"The Walking Dead" returns to AMC October 13.
