The zombie drama is rumoured to have been picked up for a fourth run, though AMC is yet to officially confirm if the series will continue past its current third season.

"As far as story goes, we certainly have concepts of bringing us into season four, and I even have concepts I haven't shared with anybody about season five," Mazzara told Assignment X.
"I don't want to get too far ahead of myself, but I think about this stuff constantly."
The exec producer added that he does also "have a plan in mind" as to how The Walking Dead will eventually conclude.
"A lot of that [plan] is thematic and conceptual," he explained. "I come up with emotional feeling I want people to take away each season and probably the series. I have that in mind."
The Walking Dead airs on FX in the UK and on AMC in the US.
