AMC's latest series "The Walking Dead", based off a graphic novel of the same name about a zombie, has defied expectations to become one of the few success stories of the fall television season.

The premiere of the show nabbed 5.3 million viewers to become the most-watched premiere of any AMC television series, and the show has only gone on to expand its audience.

Now as the season winds to a close on Sunday night, the show's star, Andrew Lincoln, talked to media outlets about what is in store for the episode.

Lincoln plays Rick Grimes on the show, a deputy sheriff in Georgia who leads a pack of survivors during the zombie apocalypse. In the previous episode, Grimes leads the survivors to the CDC headquarters. In the finale they will meet a researcher who is studying the virus that turns humans into zombies.

"They're obviously looking for safety and some answers, and they think they potentially have salvation," Lincoln told TV Guide. "And then over a couple hours they realize this man isn't who they think he is. They realize extremely quickly that they may be in more fear of their life being in the CDC."

So will Rick's role as the leader be threatened in the finale? Lincoln tells the magazine, "The great thing about the world that they inhabit is that there are no right answers, there are no right decisions made. Everything seems to be a compromise at the moment, and it's just about how good a compromise you can make."

As for next season, the executive producer of the series Gale Anne Hurd, tells Entertainment Weekly, " I think Frank [Darabont, who developed the series and directs episodes] and Robert [Kirkman, writer of the "Walking Dead" comic and an executive producer on the show] will sit down early next year, to begin mapping it out."

She added that many of the stars will be returning. "Every one of the principal cast is signed up for multiple seasons."

The season finale of "The Walking Dead" airs Sunday, December 5 at 10 p.m. on AMC.
