AMC's The Walking Dead is firming up its ranks for season four.
Just days after the zombie drama's bloody season three finale, the series based on the comics created by Robert Kirkman has promoted three familiar faces to series regular.
New additions Chad Coleman (Tyreese), Sonequa Martin-Green (Sasha) and Emily Kinney (Beth) will rejoin the series full-time when The Walking Dead returns in October, The Hollywood Reporter has learned. They join David Morrissey(the Governor) as regulars as the series will start off next season at the newly repopulated prison.
In addition, Melissa Ponzio -- who played Karen, the lone survivor of the Governor's attack on his own Woodbury army who helped bring peace between Tyreese and Rick in the finale -- will return to the series as a recurring guest star in season four.
Coleman joined the series in November in a recurring role as fan favorite Tyreese, who first appeared in the seventh issue of Kirkman's long-running Image comic. During season three, Tyreese played a central role in saving the women and children of Woodbury from the Governor, rejoining Rick -- with his outspoken sister, Sasha (Martin-Green), who is a new character to the Walking Dead universe.
Kinney, who plays Hershel's youngest daughter Beth, has been with the series since the second episode of season two, and will likely continue to have a larger story as she helps the group care for Rick's (Andrew Lincoln) newborn daughter, Judith, and someone who's closest in age to his son troubled son, Carl (Chandler Riggs).
"[Rick] is letting the people of Woodbury in and tying to tell Carl that these people are like us, you have to be open to this and the only way to survive in this world is to have people and be in a community. That's going to be a big part of season four," Kirkman told THR after the finale, which claimed the lives of Milton (Dallas Roberts) and Andrea (Laurie Holden).
During its record-breaking fourth season, The Walking Dead lost a long roster of characters. In addition to Holden -- who was with the series since its premiere -- Rick's wife Lori (Sarah Wayne Callies) was shockingly killed off in early in its third year along with regular T-Dog (IronE Singleton), among other recurring players including Daryl's (Norman Reedus) brother Merle (Michael Rooker). The additions help firm up the show's ranks as the show's returning villan the Governor is still hungry for Michonne (Danai Gurira) and Rick's blood.
Kinney is repped by Abrams Artists, Authentic Talent and Literary; Coleman is with Talent Works and Vanguard; Martin-Green is with Gersh and Principal Entertainment; and Ponzio (Teen Wolf, The Following) is with People Store and Kass Management.
The Walking Dead returns to AMC in October with new showrunner Scott M. Gimple.
