One of the executive producers of The Walking Dead has predicted that the death toll will rise when the Zombie series returns for the second half of season three.

The Hollywood Reporter quotes Emmy-winning VFX designer Greg Nicotero as saying there might be more bull’s-eyes on the backs of some of the drama’s regular castmembers.

The first half of series three saw the deaths of original cast-members Lori (Sarah Wayne Callies) and T-Dog (IronE Singleton) and ended with Daryl (Norman Reedus) being pitted against his brother Merle (Michael Rooker) after being capture during the raid on Woodbury to rescue Glenn and Maggie.

Nicotero said "We've established a certain scenario on our show where nobody is safe - and certainly in the back-half of our season, it doesn't get easy for anybody," adding "We have the whole Woodbury community with the Governor (David Morrissey) and our principal cast. We'll probably end our season minus a castmember or two."

He also said that Andrea (Laurie Holden) would be very prominent in the show when it returns as she begins to see another side to the Governor and realises she has been "completely hoodwinked" by him.

Holden said "Andrea's eyes are now opening; she had no idea that Rick and the others were still alive. Now she's learning that the group is not only alive but that one of her friends has been captured by the man she's been romantically involved with. Her head is exploding."
