"The Walking Dead' is based on a comic book by Robert Kirkman, but the first three seasons were just influenced by the comics, not based on the stories there. However, according to IO9 on Sept. 2, new showrunner Scott Gimple said they are going to start pulling stories straight from the comics starting in season four.
With the addition of the character of Tyrone to the cast, there is one more addition to tie it closer to the comics. But, Gimple said that the stories would have to change when it comes to who does what in the stories because people from the comics are dead now on the TV show and some characters from the show never existed in the comics.
Gimple said that fans of the comics will know exactly which stories are which when they show them on the television show, and while some characters will change, the emotional thrust of the stories will be in place.
Executive producer Greg Nicotero said that one episode will be taken "almost verbatim" from the comics.
Added to that, actor David Morrisey spoke about his character of The Governor. He said that what his character at the end of season three would weigh heavily on him throughout the fourth season and will pattern who he becomes and which side he ends up on.
The Walking Dead returns Sunday, Oct. 13, at 9 p.m. on AMC.
